Question : The ratio of the radii of two cylinders is $2:3$ and the ratio of their heights is $5:3$. The ratio of their volumes will be:
Option 1: $9:4$
Option 2: $20:27$
Option 3: $4:9$
Option 4: $27:20$
Correct Answer: $20:27$
Solution : Given: The ratio of the radii of two cylinders is $2:3$ and the ratio of their heights is $5:3$. Let the radii of the first cylinder = $2r$ units So, the radii of the second cylinder = $3r$ units Also, let their heights be $5h$
Question : A moneylender claims to lend money at the rate of 10% per annum simple interest. However, he takes the interest in advance when he lends a sum for one year. At what interest rate does he lend the money?
Option 1: $10$%
Option 2: $10\frac{1}{9}$%
Option 3: $11$%
Option 4: $11\frac{1}{9}$%
Correct Answer: $11\frac{1}{9}$%
Solution : Given: Rate = 10% Let the amount lent be Rs. 100. Interest =10% of 100 = Rs. 10 Actual amount = 100 – 10 = Rs. 90 Actual rate = $10×\frac{100}{90}=11\frac{1}{9}$% Hence, the correct answer is $11\frac{1}{9}$%.
Question : Directions: Select the set in which the numbers are related in the same way as the numbers of the following sets. (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 – Operations on 13 such as adding/subtracting/multiplying etc. 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is NOT allowed.)

Question : If the difference between the average of x, y and y, z is 12, then the difference between x and z is:
Option 1: 24
Option 2: 48
Option 3: 12
Option 4: 6
Correct Answer: 24
Solution : Given: The difference between the average of (x, y) and (y, z) is 12. According to the question, $\frac{\text{x+y}}{2}$–$\frac{\text{y+z}}{2}$ = 12 ⇒ x + y – y – z = 24 ⇒ x – z = 24 Hence, the correct answer is 24.
