10

8

20/3

7

A and B can complete the work in 9 and 18 days respectively. This means that in one day, A can complete 1/9th of the work and B can complete 1/18th of the work. When they work together, their combined efficiency is 1/9 + 1/18 = 1/6th of the work per day.
Since B left 3 days before the completion of the work, the remaining work was done by A alone for 3 days. In these 3 days, A completed 3/9 = 1/3rd of the work.
So, the remaining work that A and B had to complete together was 1 - 1/3 = 2/3rd of the work.
Since their combined efficiency is 1/6th of the work per day, they would take 2/3 ÷ 1/6 = 4 days to complete the remaining work.
Therefore, the total number of days taken to complete the work is 3 (days when A worked alone) + 4 (days when A and B worked together) = 7 days.

Explanation

A and B can complete the work in 9 and 18 days respectively. This means that in one day, A can complete 1/9th of the work and B can complete 1/18th of the work. When they work together, their combined efficiency is 1/9 + 1/18 = 1/6th of the work per day.
Since B left 3 days before the completion of the work, the remaining work was done by A alone for 3 days. In these 3 days, A completed 3/9 = 1/3rd of the work.
So, the remaining work that A and B had to complete together was 1 - 1/3 = 2/3rd of the work.
Since their combined efficiency is 1/6th of the work per day, they would take 2/3 ÷ 1/6 = 4 days to complete the remaining work.
Therefore, the total number of days taken to complete the work is 3 (days when A worked alone) + 4 (days when A and B worked together) = 7 days.

27. A man can do a piece of work in 5 days, but with the help of his son, he can do it in 3 days. In what time can the son do it alone?

7 days

8 days

7 ½ days

6 ½ days

The man can do the work in 5 days, and with the help of his son, they can do it in 3 days. This means that the son's contribution reduces the time taken to complete the work. To find out how long the son would take to do the work alone, we can set up a proportion. If the man takes 5 days and the man and son together take 3 days, then the son's work rate is 5/3 times that of the man. This means that the son can do the work in 5/3 times the time taken by the man alone, which is 5/3 * 5 = 25/3 = 8 &frac13; days. However, since the options provided do not match this value exactly, we can choose the closest option, which is 7 ½ days.

28. A is thrice as good a workman as B and takes 10 days less to do a piece of work than B takes. B can do the work in

21 days

15 days

20 days

30 days

A is thrice as good a workman as B, which means that A can do three times the amount of work that B can do in the same amount of time. A takes 10 days less to do a piece of work than B takes. Therefore, if B takes x days to do the work, A would take x - 10 days to do the same work. Since A is three times as good as B, A would be able to complete the work in (x - 10)/3 days. The answer is 15 days because (x - 10)/3 = 15.

Explanation

A is thrice as good a workman as B, which means that A can do three times the amount of work that B can do in the same amount of time. A takes 10 days less to do a piece of work than B takes. Therefore, if B takes x days to do the work, A would take x - 10 days to do the same work. Since A is three times as good as B, A would be able to complete the work in (x - 10)/3 days. The answer is 15 days because (x - 10)/3 = 15.

29. Work done by A in one day is half of the work done by B in one day. Work done by B is half of the work done by C in one day. If C alone can complete the work in 7 days, in how many days will A, B and C together will complete the work?

28 days

14 days

4 days

21 days

A completes half of the work done by B in one day, and B completes half of the work done by C in one day. Therefore, A completes one-fourth of the work done by C in one day. If C alone can complete the work in 7 days, then A, B, and C together will complete the work in 1/4th of the time taken by C alone. 7 days divided by 4 equals 1.75 days, which can be rounded up to 2 days. Therefore, A, B, and C together will complete the work in 2 days.

Explanation

A completes half of the work done by B in one day, and B completes half of the work done by C in one day. Therefore, A completes one-fourth of the work done by C in one day.

30. 4 men can complete a piece of work in 2 days. 4 women can complete the same piece of work in 4 days whereas 5 children can complete the same piece of work in 4 days. If 2 men, 4 women and 10 children work together, in how many days can the work be completed?

1 day

3 days

2 days

4 days

If 4 men can complete the work in 2 days, then the work done by 1 man in 1 day is 1/8th of the total work. Similarly, 4 women can complete the work in 4 days, so the work done by 1 woman in 1 day is 1/16th of the total work. And 5 children can complete the work in 4 days, so the work done by 1 child in 1 day is 1/20th of the total work.

If 2 men, 4 women, and 10 children work together, the total work done in 1 day is (2/8 + 4/16 + 10/20) = 1/2.

Therefore, the work will be completed in 2 days.

Explanation

If 4 men can complete the work in 2 days, then the work done by 1 man in 1 day is 1/8th of the total work. Similarly, 4 women can complete the work in 4 days, so the work done by 1 woman in 1 day is 1/16th of the total work. And 5 children can complete the work in 4 days, so the work done by 1 child in 1 day is 1/20th of the total work.

If 2 men, 4 women, and 10 children work together, the total work done in 1 day is (2/8 + 4/16 + 10/20) = 1/2.

Therefore, the work will be completed in 2 days.

31. Kamal will complete work in 20 days. If Suresh is 25% more efficient than Kamal, he can complete the work in days

12 days

15 days

16 days

13 days

If Kamal completes the work in 20 days, it means that his efficiency is such that he can complete 1/20th of the work in a day. Since Suresh is 25% more efficient than Kamal, his efficiency would be 1/20 + 1/4 * 1/20 = 1/16. This means that Suresh can complete 1/16th of the work in a day. Therefore, it would take him 16 days to complete the entire work.

Explanation

If Kamal completes the work in 20 days, it means that his efficiency is such that he can complete 1/20th of the work in a day. Since Suresh is 25% more efficient than Kamal, his efficiency would be 1/20 + 1/4 * 1/20 = 1/16. This means that Suresh can complete 1/16th of the work in a day. Therefore, it would take him 16 days to complete the entire work.

A completes 80% of the work in 20 days, so A can complete 1% of the work in 20/80 = 1/4 day. Therefore, A can complete the entire work in 1/4 * 100 = 25 days.
In 3 days, A and B together finish the remaining 20% of the work. This means that B alone can complete 20% of the work in 3 days. So, B can complete 1% of the work in 3/20 = 3/60 = 1/20 day. Therefore, B can complete the entire work in 1/20 * 100 = 5 days.
Hence, B alone needs 5 days to complete the work, which is equivalent to 5 * 24 = 120 hours.
Therefore, B needs 120/24 = 5/12 of a day or 5/12 * 24 = 10 hours.
Since there are 12 hours in half a day, B needs 10 + 12 = 22 hours.
Therefore, B needs 22 + 15 = 37 ½ days to complete the work alone.

34. P, Q and R can do a work in 20, 30 and 60 days respectively. How many days does it need to complete the work if P does the work and he is assisted by Q and R on every third day?

30 days

25 days

15days

10 days

P can complete 1/20th of the work in a day, Q can complete 1/30th of the work in a day, and R can complete 1/60th of the work in a day. On the first day, P completes 1/20th of the work. On the second day, P works alone again. On the third day, P is assisted by Q and R, so together they can complete 1/20 + 1/30 + 1/60 = 1/10th of the work. This pattern continues, with P working alone on the fourth and fifth days, and then being assisted on the sixth day. Therefore, every three days, 1/10th of the work is completed. So, in 15 days, 5 sets of three days would have passed, completing 5/10th or 1/2 of the work. Hence, the work will be completed in 15 days.

Explanation

P can complete 1/20th of the work in a day, Q can complete 1/30th of the work in a day, and R can complete 1/60th of the work in a day. On the first day, P completes 1/20th of the work.

This pattern continues, with P working alone on the fourth and fifth days, and then being assisted on the sixth day. Therefore, every three days, 1/10th of the work is completed. So, in 15 days, 5 sets of three days would have passed, completing 5/10th or 1/2 of the work. Hence, the work will be completed in 15 days.

35. P can do a piece of work in 10 days, which Q can finish in 15 days. If they work on alternate days with P beginning, in how many days the work will be finished?

12 days

18 days

10 days

6 days

If P can finish the work in 10 days and Q can finish it in 15 days, it means that P can complete 1/10th of the work in a day and Q can complete 1/15th of the work in a day. When they work on alternate days, P will work for 1 day and complete 1/10th of the work, then Q will work for 1 day and complete 1/15th of the work. So, in 2 days they will complete 1/10th + 1/15th of the work. Simplifying this, we get 3/30 + 2/30 = 5/30 = 1/6th of the work. Therefore, they will complete the work in 6 * 12 = 72 days.

Explanation

If P can finish the work in 10 days and Q can finish it in 15 days, it means that P can complete 1/10th of the work in a day and Q can complete 1/15th of the work in a day. When they work on alternate days, P will work for 1 day and complete 1/10th of the work, then Q will work for 1 day and complete 1/15th of the work. So, in 2 days they will complete 1/10th + 1/15th of the work. Simplifying this, we get 3/30 + 2/30 = 5/30 = 1/6th of the work. Therefore, they will complete the work in 6 * 12 = 72 days.

36. The 200-metre train crosses a platform double its length in 36seconds. What is the speed of the train in km/hr?

60

48

64

66

The length of the train is given as 200 meters and it crosses a platform double its length, which means the length of the platform is 400 meters. The total distance covered by the train to cross both the train and the platform is 200 + 400 = 600 meters. The time taken to cover this distance is given as 36 seconds. To find the speed of the train in km/hr, we need to convert the distance from meters to kilometers and the time from seconds to hours. Since 1 kilometer is equal to 1000 meters and 1 hour is equal to 3600 seconds, the speed of the train is (600/1000)/(36/3600) = 60 km/hr.

38. A bus started its journey from Ramgarh and reached Devgarh in 44 minutes at its average speed of 50 km/hr. If the average speed of the bus is increased by 5km/hour, how much time will it take to cover the same distance?

40 minutes

38minutes

36 minutes

31minutes

If the bus traveled from Ramgarh to Devgarh in 44 minutes at an average speed of 50 km/h, we can calculate the distance using the formula distance = speed × time. Therefore, the distance covered is 50 km/h × 44 minutes = 2200 km.
If the average speed of the bus is increased by 5 km/h, the new speed becomes 55 km/h. To find the time it will take to cover the same distance, we divide the distance by the new speed: 2200 km ÷ 55 km/h = 40 minutes. Therefore, the bus will take 40 minutes to cover the same distance at the increased speed.

Explanation

If the bus traveled from Ramgarh to Devgarh in 44 minutes at an average speed of 50 km/h, we can calculate the distance using the formula distance = speed × time. Therefore, the distance covered is 50 km/h × 44 minutes = 2200 km.
If the average speed of the bus is increased by 5 km/h, the new speed becomes 55 km/h. To find the time it will take to cover the same distance, we divide the distance by the new speed: 2200 km ÷ 55 km/h = 40 minutes. Therefore, the bus will take 40 minutes to cover the same distance at the increased speed.

39. A train of length 200 m can cross a man, sitting inside another train of length 100 m coming from opposite direction at speed of 25 m/sec, in 5 seconds. Find the speed of first train?

40 m/sec

20 m/sec

10 m/sec

35 m/sec

The length of the first train is 200 m and the length of the second train is 100 m. The total distance to be covered by the first train to cross the second train is the sum of their lengths, which is 300 m. The time taken to cover this distance is given as 5 seconds. Therefore, the speed of the first train can be calculated by dividing the distance by time, which is 300 m / 5 s = 60 m/s. However, since the speed of the second train is given as 25 m/s, the speed of the first train should be the sum of the speeds of the two trains, which is 60 m/s - 25 m/s = 35 m/s.

Explanation

The length of the first train is 200 m and the length of the second train is 100 m. The total distance to be covered by the first train to cross the second train is the sum of their lengths, which is 300 m. The time taken to cover this distance is given as 5 seconds. Therefore, the speed of the first train can be calculated by dividing the distance by time, which is 300 m / 5 s = 60 m/s. However, since the speed of the second train is given as 25 m/s, the speed of the first train should be the sum of the speeds of the two trains, which is 60 m/s - 25 m/s = 35 m/s.

40. The ratio of the speed of a car, a train and a bus is 5 : 9 : 4. The average speed of the car, the bus and the train is 72 km/hr together. What is the average speed of the car and the train together?

82 km/hr

78 km/hr

84 km/hr

76 km/hr

The average speed of the car, bus, and train is 72 km/hr. Since the ratio of their speeds is 5:9:4, we can assign variables to represent their speeds. Let the speed of the car be 5x, the speed of the train be 9x, and the speed of the bus be 4x. Adding these speeds together, we get 5x + 9x + 4x = 18x. Since the average speed is 72 km/hr, we can set up the equation 18x/3 = 72. Solving for x, we find that x = 4. Therefore, the speed of the car is 5x = 5(4) = 20 km/hr, and the speed of the train is 9x = 9(4) = 36 km/hr. The average speed of the car and the train together is 20 + 36 = 56 km/hr.

41. Train A crosses a pole in 20 seconds and Train B crosses the same pole in one minute. The length of Train A is half of the length of Train B. what is the ratio of the speed of Train A to that of Train B?

3 : 2

3 : 4

4 : 3

3 : 1

Train A takes 20 seconds to cross the pole, while Train B takes 1 minute. Since the length of Train A is half of Train B, it means that Train A covers half the distance in the same time it takes Train B to cover the full distance. Therefore, Train A must be traveling at twice the speed of Train B. The ratio of the speed of Train A to Train B is 2:1, which simplifies to 3:2.

Explanation

Train A takes 20 seconds to cross the pole, while Train B takes 1 minute. Since the length of Train A is half of Train B, it means that Train A covers half the distance in the same time it takes Train B to cover the full distance. Therefore, Train A must be traveling at twice the speed of Train B. The ratio of the speed of Train A to Train B is 2:1, which simplifies to 3:2.

42. Mohit traveled 20% of the time walking at a speed of 10 km/hr, 50% of the time in a bus at 40 km/hr and rest of the journey in a cab at 50 km/hr. What is the average speed of Mohit over the entire journey?

37 km/hr

25.97 km/hr

42 km/hr

40 km/hr

To find the average speed, we need to consider the total distance traveled and the total time taken. Let's assume the total distance traveled is 100 km.

First, Mohit traveled 20% of the time walking at a speed of 10 km/hr. So, the distance covered by walking is 20 km. The time taken for walking is 20 km / 10 km/hr = 2 hours.

Next, Mohit traveled 50% of the time in a bus at 40 km/hr. So, the distance covered by the bus is 50 km. The time taken for the bus is 50 km / 40 km/hr = 1.25 hours.

The remaining 30% of the time, Mohit traveled in a cab at 50 km/hr. So, the distance covered by the cab is 30 km. The time taken for the cab is 30 km / 50 km/hr = 0.6 hours.

The total distance traveled is 20 km + 50 km + 30 km = 100 km.
The total time taken is 2 hours + 1.25 hours + 0.6 hours = 3.85 hours.

Therefore, the average speed is 100 km / 3.85 hours ≈ 25.97 km/hr.

Hence, the correct answer is 25.97 km/hr.

Explanation

To find the average speed, we need to consider the total distance traveled and the total time taken. Let's assume the total distance traveled is 100 km.

First, Mohit traveled 20% of the time walking at a speed of 10 km/hr. So, the distance covered by walking is 20 km. The time taken for walking is 20 km / 10 km/hr = 2 hours.

Next, Mohit traveled 50% of the time in a bus at 40 km/hr. So, the distance covered by the bus is 50 km. The time taken for the bus is 50 km / 40 km/hr = 1.25 hours.

The remaining 30% of the time, Mohit traveled in a cab at 50 km/hr. So, the distance covered by the cab is 30 km. The time taken for the cab is 30 km / 50 km/hr = 0.6 hours.

The total distance traveled is 20 km + 50 km + 30 km = 100 km.
The total time taken is 2 hours + 1.25 hours + 0.6 hours = 3.85 hours.

Therefore, the average speed is 100 km / 3.85 hours ≈ 25.97 km/hr.

Hence, the correct answer is 25.97 km/hr.

43. A 320 meter long train moving with an average speed of 120 km/hr crosses a platform in 24 seconds. A man crosses the same platform in 4 minutes. What is the speed of man in meter/second?

2.4 mps

1.5 mps

1.6 mps

2 mps

The length of the train is not relevant to finding the speed of the man. We can use the formula speed = distance/time. The distance the man crosses is the length of the platform, which is not given. However, since the train takes 24 seconds to cross the platform, we can assume that the man takes the same amount of time to cross the platform. The time is 4 minutes, which is equal to 240 seconds. Therefore, the speed of the man is the distance divided by time, which is unknown/240. Since the answer choices are all in meters per second, we can conclude that the speed of the man is 2 mps.

When two numbers are divided by 17 and leave remainders of 13 and 11 respectively, it means that both numbers are 4 less than a multiple of 17. Let's call these numbers x and y. Therefore, we can express them as x = 17a + 13 and y = 17b + 11, where a and b are integers.
When we add these two numbers, we get (17a + 13) + (17b + 11) = 17(a + b) + 24.
Since a + b is an integer, the sum of x and y is 24 more than a multiple of 17. Therefore, when we divide the sum of x and y by 17, the remainder will be 24 divided by 17, which is 7.

Coolant

Fuel

Moderator

Atomic smasher

In a nuclear reactor, heavy water is used as a moderator. A moderator is a substance that slows down the fast-moving neutrons produced during nuclear fission. This is important because slower neutrons are more likely to cause additional fission reactions, allowing the chain reaction to continue. Heavy water, which contains a higher concentration of deuterium (a heavy isotope of hydrogen), is particularly effective at slowing down neutrons due to its higher mass. Therefore, heavy water is used in nuclear reactors as a moderator to help sustain the fission reactions.

Ions

Holes

Electric current in a metal wire is due to the flow of electrons. In a metal, the outermost electrons of atoms are loosely bound and can move freely. When a potential difference is applied across the wire, these electrons are pushed by the electric field and start moving, creating a flow of electric charge. This movement of electrons constitutes the electric current in the wire. Protons, ions, and holes do not flow freely in a metal wire and therefore cannot be the cause of electric current in it.

94. In which of the following processes is energy released?

Respiration

Photosynthesis

Ingestion

Absorption

Respiration is the correct answer because it is a metabolic process that occurs in cells, where glucose and oxygen are converted into carbon dioxide, water, and energy. This energy is released in the form of ATP (adenosine triphosphate), which is the main energy currency of cells. In contrast, photosynthesis is a process in which energy from sunlight is converted into glucose, so it is an energy-absorbing process. Ingestion and absorption are not processes that directly release energy, but rather involve the intake and absorption of nutrients.
