The sum of two numbers is 15 and their geometric mean is 20% lower than their arithmetic mean. Find the Numbers
- A.
11, 4
- B.
12, 3
- C.
13, 2
- D.
10, 5
Correct Answer
B. 12, 3Explanation
The arithmetic mean of two numbers is the sum of the numbers divided by 2. In this case, the arithmetic mean is (12+3)/2 = 7.5. The geometric mean is the square root of the product of the numbers. Let the numbers be x and y. We know that x+y=15, so y=15-x. The geometric mean is then sqrt(x*(15-x)). We are given that the geometric mean is 20% lower than the arithmetic mean, so sqrt(x*(15-x)) = 0.8*7.5. Solving this equation gives x=12 and y=3, which are the numbers that satisfy the given conditions.Rate this question:

1012
Correct Answer
D. 1012Explanation
The question asks for the least common multiple (LCM) of 11 that leaves a remainder of 4 when divided by 8, 9, 12, and 14. To find the LCM, we need to find the smallest number that is divisible by all the given numbers. We can start by finding the LCM of 8, 9, 12, and 14, which is 504. Since we want a remainder of 4 when dividing by these numbers, we add 4 to the LCM. Therefore, the LCM of 11 that satisfies the given conditions is 508. However, this is not one of the answer choices. The closest option is 1012, which is double the LCM of 11. Hence, the correct answer is 1012.Rate this question:

The LCM of two numbers is 12 times their HCF. The sum of HCF and LCM is 403. if one of the number is 93 what will be the other
- A.
134
- B.
124
- C.
128
- D.
126
Correct Answer
B. 124Explanation
Let's assume the HCF of the two numbers is x. Given that the LCM is 12 times the HCF, we can write the equation LCM = 12x. The sum of the HCF and LCM is 403, so we have the equation x + 12x = 403. Simplifying this equation, we get 13x = 403. Dividing both sides by 13, we find that x = 31. Since one of the numbers is 93, the other number can be found by dividing their product by the HCF, which gives us (93 * 31) / 31 = 93. Therefore, the other number is 124.Rate this question:

The speed of the train in going from Nagpur to allahabad is 100 km/hr while when coming from allahabad to nagpur, its speed is 150 km/hr What will be the average speed During the Journey
- A.
125 km/hr
- B.
120 km/hr
- C.
75 km/hr
- D.
135 km/hr
Correct Answer
B. 120 km/hrExplanation
The average speed during the journey can be calculated by taking the total distance traveled and dividing it by the total time taken. Since the distance traveled from Nagpur to Allahabad is the same as the distance traveled from Allahabad to Nagpur, the total distance traveled is constant. Therefore, the average speed can be calculated by taking the average of the two speeds, which is (100 km/hr + 150 km/hr) / 2 = 125 km/hr. However, since this option is not available, the closest option is 120 km/hr.Rate this question:

What will be Average of the First 97 Natural numbers
- A.
47
- B.
37
- C.

Correct Answer
C. 49Explanation
The average of a set of numbers is found by dividing the sum of the numbers by the count of the numbers. In this case, the first 97 natural numbers start from 1 and go up to 97. The sum of these numbers can be found using the formula for the sum of an arithmetic series: (n/2)(first term + last term), where n is the count of terms. Plugging in the values, we get (97/2)(1 + 97) = 97(98)/2 = 4753. Dividing this sum by 97, the count of numbers, gives us an average of 49. Therefore, the correct answer is 49.Rate this question:

The ratio between two numbers is 3 : 4 and their LCM is 180. What will be the first number
- A.
60
- B.
45
- C.
15
- D.
20
Correct Answer
B. 45Explanation
The ratio between two numbers is 3:4, which means that for every 3 units of the first number, there are 4 units of the second number. Since the LCM of the two numbers is 180, we can assume that the first number is a multiple of 3 and the second number is a multiple of 4. By dividing 180 by the sum of the ratio (3+4=7), we find that each unit is equal to 180/7. Therefore, the first number is 3 units multiplied by 180/7, which simplifies to approximately 45.Rate this question:

A mixture contains milk and water in the ratio 5 : 1 on adding 5 litres of water, the ratio of milk to water becomes 5 : 2, the quantity of milk in the mixture is
- A.
16 litres
- B.
25 litres
- C.
32.5 litres
- D.
22.75 litres
Correct Answer
B. 25 litresExplanation
Let's assume the initial quantity of the mixture is 5x litres of milk and x litres of water.
According to the given information, the ratio of milk to water is 5:1.
So, 5x/(x) = 5/1
Simplifying this equation, we get 5x = 5x
Now, when 5 litres of water is added, the new quantity of water becomes x + 5 litres.
The new ratio of milk to water is given as 5:2.
So, 5x/(x + 5) = 5/2
Cross-multiplying and simplifying, we get 10x = 5x + 25
Solving this equation, we find x = 5
Therefore, the initial quantity of milk in the mixture is 5x = 5 * 5 = 25 litres.
Hence, the correct answer is 25 litres.Rate this question:

To find the number that must be added to each of the given numbers to make the ratio of the first two numbers equal to the ratio of the last two numbers, we need to calculate the difference between the first two numbers and the last two numbers.
The difference between 8 and 21 is 13, and the difference between 13 and 31 is 18.
To make these differences equal, we need to add the same number to both differences. Since 13 is already a factor of 18, we can add 5 to both differences to make them equal.
Therefore, the number that must be added to each of the given numbers is 5.Rate this question:

- A.
96%
- B.
95%
- C.
98%
- D.
94%
Correct Answer
A. 96%Explanation
When a number is mistakenly divided by 5 instead of being multiplied by 5, the result will be 1/5th of the correct value. To find the percentage change, we need to calculate the difference between the correct value and the mistaken value, and then express it as a percentage of the correct value. In this case, the correct value would be 5 times the mistaken value. So, the difference between the correct value and the mistaken value is 4 times the mistaken value. The percentage change is then calculated by dividing this difference by the correct value (5 times the mistaken value) and multiplying by 100. Simplifying this expression gives us 4/5 * 100 which equals 80%. Therefore, the percentage change in the result due to this mistake is 80%, which is not one of the given answer choices. Hence, the correct answer is not available.Rate this question:

The price of rice falls by 20%. How much rice can be bought now with the money that was sufficient to buy 20 kg or rice previously
- A.
10 kg
- B.
15 kg
- C.
25 kg
- D.

Correct Answer
C. 25 kgExplanation
When the price of rice falls by 20%, it means that the price is now 80% of the original price. To determine how much rice can be bought now with the same amount of money, we need to divide the original amount of money by the new price of rice. Since the price is now 80% of the original price, we can buy 1.25 times the amount of rice we could buy previously. Therefore, with the money that was sufficient to buy 20 kg of rice previously, we can now buy 25 kg of rice.Rate this question:

1%
- B.
2%
- C.

Correct Answer
A. 1%Explanation
When the tax on a commodity is diminished by 10%, it means that the tax rate is reduced by 10%. At the same time, the consumption of the commodity increases by 10%. These two factors have opposing effects on revenue. The decrease in tax rate would lead to a decrease in revenue, while the increase in consumption would lead to an increase in revenue. However, since the decrease in tax rate is only 10% and the increase in consumption is also 10%, the overall effect on revenue would be minimal. Therefore, the revenue would decrease by approximately 1%.Rate this question:

The length of a rectangle is increased by 60% by what percent would the width have to be decreased to maintain the same area
- A.
74/2 %
- B.
60%
- C.
75%
- D.
70%
Correct Answer
A. 74/2 %Explanation
To maintain the same area of a rectangle after increasing the length by 60%, the width would need to be decreased by a certain percentage. The correct answer is 74/2%. This can be calculated by using the formula for the area of a rectangle, which is length multiplied by width. Since the area needs to remain the same, the new length would be 1.6 times the original length. To find the new width, we can divide the original area by the new length. This gives us the original width divided by 1.6. To find the percentage decrease, we subtract the new width from the original width, divide by the original width, and multiply by 100. The calculation comes out to be 74/2%.Rate this question:

C. 30%Explanation
The surface area of a sphere is given by the formula 4πr^2, where r is the radius. The volume of a sphere is given by the formula (4/3)πr^3. Substituting the given radius of 10 cm into these formulas, we find that the surface area is 400π cm^2 and the volume is approximately 4188.79π cm^3. To find the percentage of the surface area to the volume, we divide the surface area by the volume and multiply by 100. This gives us (400π / 4188.79π) * 100 ≈ 9.55%.

The market price of a table is Rs. 1200 , which is 20% above the cost price . It is sold at a discount of 10 % on the marked price. Find the profit percent .
- A.
10%
- B.
8%
- C.
7.50%
- D.
6%
Correct Answer
B. 8%Explanation
The cost price of the table can be found by dividing the market price by 1 plus the percentage increase, which is 1200 / (1 + 20/100) = 1000. The selling price is then found by subtracting the discount percentage from 100% and multiplying it by the market price, which is (100 - 10)% * 1200 = 1080. The profit is the difference between the selling price and the cost price, which is 1080 - 1000 = 80. Finally, the profit percent is found by dividing the profit by the cost price and multiplying it by 100, which is (80 / 1000) * 100 = 8%.Rate this question:
