Given below are two quantities named I and II. Based on the given information, you have to determine the relation between the two quantities. You should use the given data and your knowledge of Mathematics to choose among the possible answers. A man has two balls. The ratio of radius of first ball to that of the second ball is 7 : 3. Quantity I: If man cut the first ball from middle and difference between total surface area of part of first ball and total surface area of second ball is 1538.46cm2, then find the radius of smaller ball. Quantity II: If the sum of radius of two balls is 30, then what is the radius of first ball?

A

If Quantity I > Quantity II

B

If Quantity I < Quantity II

C

If Quantity I ≥ Quantity II

D

If Quantity I ≤ Quantity II

Compare the values of the two quantities in the question and answer. Quantity 1: A bag contains 20 balls which are red, green and blue. Find the number of red balls in the bag, if the probability of picking a blue ball is 2/5 and that of either a red or a blue ball is 3/4. Quantity 2: A bag contains 25 balls which are red, green and blue. The probability of picking a red ball first is 2/5. If the first ball was red and without keeping it back, probability of picking a blue ball is 1/3, find the number of green balls.

A

Quantity 1 > Quantity 2

B

Quantity 1 < Quantity 2

C

Quantity 1 ≥ Quantity 2

D

Quantity 1 ≤ Quantity 2

E
