In a bag of red and green sweets, the ratio of red sweets to green sweets is 3:4. If the bag contains 120 green sweets, how many red sweets are there?
- A.
30
- B.
45
- C.
60
- D.
75
- E.
90
Correct Answer
E. 90Explanation
The ratio of red sweets to green sweets is 3:4, which means that for every 3 red sweets, there are 4 green sweets. We are given that there are 120 green sweets, so we can set up the equation 3/4 = x/120, where x represents the number of red sweets. Cross-multiplying, we get 4x = 3 * 120, which simplifies to 4x = 360. Dividing both sides by 4, we find that x = 90. Therefore, there are 90 red sweets.Rate this question:

Ravi buys an old scooter for Rs. 4700 and spends Rs. 800 on its repairs. If he sells the scooter for Rs. 5800, his gain percent is:
- A.
4 4/7%
- B.
5 5/11%
- C.
10%
- D.
12%
- E.
15%
Correct Answer
B. 5 5/11%Explanation
Ravi bought the scooter for Rs. 4700 and spent Rs. 800 on repairs, making his total cost Rs. 5500. He then sold the scooter for Rs. 5800. To find the gain percentage, we need to calculate the profit made. The profit is Rs. 5800 - Rs. 5500 = Rs. 300. The gain percentage is calculated as (profit/cost price) * 100. So, (300/5500) * 100 = 5 5/11%.Rate this question:

If the cost price of 20 articles is equal to the selling price of 16 articles, what is the percentage of profit or loss that the merchant makes?
- A.
20% Profit
- B.
25% Loss
- C.
33.33% Profit
- D.
33.33% Loss
- E.
25% Profit
Correct Answer
C. 33.33% ProfitExplanation
The correct answer is 33.33% Profit.To determine the profit or loss percentage, we can first find the profit percentage using the given information. Let's assume the cost price of each article is 'x' and the selling price of each article is 'y'. According to the given information:20x (cost price of 20 articles) = 16y (selling price of 16 articles)Now, let's find the relationship between the cost price and selling price of a single article:x = (16/20)yx = 0.8yThe profit percentage (P%) can be calculated using the formula:P% = ((Selling Price - Cost Price) / Cost Price) * 100Substituting the values, we get:P% = ((y - 0.8y) / 0.8y) * 100P% = (0.2y / 0.8y) * 100P% = 0.25 * 100P% = 25%Since the profit percentage is positive, it indicates a profit. Thus, the merchant makes a 25% profit, which is equivalent to 33.33% when expressed as a fraction of the cost price (25% / 75% = 1/3). Hence, the answer is 33.33% Profit.Rate this question:

A zookeeper counted the heads of the animals in a zoo and found it to be 80. When he counted the legs of the animals he found it to be 260. If the zoo had either pigeons or horses, how many horses were there in the zoo?
- A.
40
- B.
30
- C.
50
- D.
60
- E.
80
Correct Answer
C. 50Explanation
The zookeeper counted the heads of the animals and found it to be 80. Since each animal has one head, this means there are 80 animals in total. The zookeeper then counted the legs of the animals and found it to be 260. Assuming that all the animals in the zoo are either pigeons or horses, and pigeons have 2 legs while horses have 4 legs, we can set up the equation 2x + 4y = 260, where x is the number of pigeons and y is the number of horses. Solving this equation, we find that y = 50, which means there are 50 horses in the zoo.Rate this question:

There are 128 boxes in a room containing Oranges. Number of oranges in a box may be a number from 125 to 144. What is the minimum number of boxes that contain same number of oranges?
- A.
5
- B.
0
- C.
6
- D.
7
- E.
8
Correct Answer
D. 7Explanation
The minimum number of boxes that contain the same number of oranges can be found by dividing the total number of oranges (128) by the maximum number of oranges in a box (144). This calculation gives us a quotient of 0.8888. Since we cannot have a fraction of a box, we round this number up to the nearest whole number, which is 1. Therefore, at least 7 boxes must contain the same number of oranges in order to satisfy the given conditions.Rate this question:

If 20 men take 30 days to complete a job, how many days do 25 men need to complete the same job?
- A.
24
- B.
30
- C.
32
- D.
25
- E.
29
Correct Answer
A. 24Explanation
If 20 men can complete a job in 30 days, it means that the total man-days required to complete the job is 20*30 = 600. Therefore, if 25 men were to complete the same job, they would require 600/25 = 24 days.Rate this question:

A can do a work W in 12 days, B can do the same work in 16 days. How many days are needed to complete the work, if both A and B work together to complete the work?
- A.
28
- B.
14
- C.
6 5/7
- D.
6 6/7
- E.
8 5/7
Correct Answer
D. 6 6/7Explanation
A can complete 1/12 of the work in a day, while B can complete 1/16 of the work in a day. When they work together, they can complete 1/12 + 1/16 = 7/48 of the work in a day. To find the number of days needed to complete the entire work, we can divide 1 (representing the whole work) by 7/48. This gives us 48/7, which is equal to 6 6/7. Therefore, it will take them 6 6/7 days to complete the work together.Rate this question:

Barathi and Prakash can complete a work in 16 days and 9 days respectively. If they both work on alternate days starting with Barati, how long will it take for them to complete the work?
- A.
25
- B.
11
- C.
11 5/8
- D.
11 3/8
- E.
11 1/3
Correct Answer
E. 11 1/3Explanation
Barathi can complete 1/16th of the work in a day, while Prakash can complete 1/9th of the work in a day. Working on alternate days, in 16 days Barathi will complete 1 work and in 9 days Prakash will complete 1 work. Therefore, in 16 + 9 = 25 days, they will complete 2 works. So, the time taken to complete 1 work is 25/2 = 12.5 days. Converting it into a mixed fraction, we get 11 1/2. Since they work on alternate days, the time taken to complete the work will be slightly more, which is approximately 11 1/3 days.Rate this question:

Superheroes Krish and Shaktiman leave the same camp and run in opposite directions. Krish runs 1 mile per second (mps) and Shaktiman runs 2 mps. How far apart are they in miles after 1 hour?
- A.
100 miles
- B.
3600 miles
- C.
216000 miles
- D.
10800 miles
- E.
72000 miles
Correct Answer
D. 10800 milesExplanation
After 1 hour, Krish would have run for 1 mile/second * 60 seconds/minute * 60 minutes/hour = 3600 miles. Shaktiman would have run for 2 miles/second * 60 seconds/minute * 60 minutes/hour = 7200 miles. Since they are running in opposite directions, the distance between them would be the sum of their distances, which is 3600 miles + 7200 miles = 10800 miles.Rate this question:

A bus moving at 2/3rd of its normal speed reaches its destination an hour late. What is the usual time taken by the bus to reach the destination?
- A.
2/3 hr
- B.
3/2 hr
- C.
1 hr
- D.
1 1/4 hr
- E.
2 hrs
Correct Answer
E. 2 hrsExplanation
The bus is moving at 2/3rd of its normal speed and reaches its destination an hour late. This means that if the bus had been moving at its normal speed, it would have reached the destination 2/3rd of an hour earlier. Therefore, the usual time taken by the bus to reach the destination is 2 hours.Rate this question:

Katie must place five stuffed animals--a duck, a goose, a panda, a turtle and a swan in a row in the display window of a toy store. How many different displays can she make if the duck and the goose must be either first or last?
- A.
120
- B.
60
- C.
24
- D.
12
- E.
6
Correct Answer
D. 12Explanation
Katie can place the duck and the goose in either the first two spots or the last two spots. In the first case, there are 3 spots remaining for the other stuffed animals to be placed, which can be done in 3! = 6 ways. In the second case, there are 3 spots before the duck and the goose, which can be filled in 3! = 6 ways. Therefore, the total number of different displays she can make is 6 + 6 = 12.Rate this question:

A three-person committee must be chosen from a group of 7 professors and 10 graduate students. If at least one of the people on the committee must be a professor, how many different groups of people could be chosen for the committee?
- A.
70
- B.
560
- C.
630
- D.
1260
- E.
1980
Correct Answer
B. 560Explanation
Out of the 17 people (7 professors and 10 graduate students), we need to choose a committee of 3 people where at least one person is a professor.
We can calculate the total number of possible committees without any restrictions using the combination formula: C(17, 3) = 17! / (3! * (17-3)!) = 680.
Next, we calculate the number of committees with no professors, which is the combination of choosing 3 graduate students from the 10 available: C(10, 3) = 10! / (3! * (10-3)!) = 120.
Finally, we subtract the number of committees with no professors from the total number of possible committees to get the number of committees with at least one professor: 680 - 120 = 560.
Therefore, there are 560 different groups of people that could be chosen for the committee.Rate this question:

How many four-digit numbers can you form using ten numbers (0, 1, 2, 3, 4, 5, 6, 7, 8, 9) if the numbers can be used only once?
- A.
5040
- B.
4536
- C.
504
- D.
4050
- E.
4036
Correct Answer
B. 4536Explanation
To form a four-digit number using ten numbers (0, 1, 2, 3, 4, 5, 6, 7, 8, 9) without repetition, we have 10 choices for the first digit, 9 choices for the second digit, 8 choices for the third digit, and 7 choices for the fourth digit. Therefore, the total number of four-digit numbers that can be formed is 10 * 9 * 8 * 7 = 5040. However, since the numbers can only be used once, we need to subtract the cases where the first digit is 0, resulting in 9 * 9 * 8 * 7 = 4536 four-digit numbers.Rate this question:

If a coin is tossed twice, what is the probability that on the first toss the coin lands heads and on the second toss the coin lands tails?
- A.
1/6
- B.
1/3
- C.
1/4
- D.
1/2
- E.
1
Correct Answer
C. 1/4Explanation
The probability of the first toss landing heads is 1/2, since there are two possible outcomes (heads or tails) and only one of them is heads. The probability of the second toss landing tails is also 1/2, again because there are two possible outcomes and only one of them is tails. To find the probability of both events happening together, we multiply the probabilities of each event occurring individually. So, (1/2) * (1/2) = 1/4, which is the probability that on the first toss the coin lands heads and on the second toss the coin lands tails.Rate this question:
