Practice questions on Ages — with answers

Try each question first, then open the answer. Explanations are included.

1. What is the present age of X? I. X is older than Y. II. Y is younger than Z.

AStatement I alone is sufficient, but Statement II alone is not sufficient
BStatement II alone is sufficient, but Statement I alone is not sufficient
CBoth statements I and II together are sufficient, but neither alone is sufficient
DBoth statements I and II together are not sufficient

Show answer

Answer: D

Neither statement provides any absolute value for X's age, and combining them still gives only relative comparisons, so together they are not sufficient.

2. What is the ratio of the present ages of P and Q? I. Ten years ago, the ratio of their ages was 1:2. II. P is younger than Q.

AStatement I alone is sufficient, but Statement II alone is not sufficient
BStatement II alone is sufficient, but Statement I alone is not sufficient
CBoth statements I and II together are sufficient, but neither alone is sufficient
DBoth statements I and II together are not sufficient

Show answer

Answer: D

The ratio ten years ago does not translate directly to the present-day ratio without knowing actual ages, and Statement II gives no numerical value. Together, the ratio still cannot be determined.

3. What is the difference between the ages of Mohan and his wife? I. Mohan is older than his wife. II. Mohan's wife is 27 years old.

AStatement I alone is sufficient, but Statement II alone is not sufficient
BStatement II alone is sufficient, but Statement I alone is not sufficient
CBoth statements I and II together are sufficient, but neither alone is sufficient
DBoth statements I and II together are not sufficient

Show answer

Answer: D

Even combined, we know Mohan is older and his wife's exact age, but Mohan's exact age is never given, so the age difference cannot be determined.

4. What is the present age of Deepak? I. Deepak's age is an odd number. II. Deepak's age is a prime number less than 20.

AStatement I alone is sufficient, but Statement II alone is not sufficient
BStatement II alone is sufficient, but Statement I alone is not sufficient
CBoth statements I and II together are sufficient, but neither alone is sufficient
DBoth statements I and II together are not sufficient

Show answer

Answer: D

Statement I alone gives too many possibilities. Statement II alone still allows multiple primes below 20 (2,3,5,7,11,13,17,19, though the odd condition removes 2). Even together, multiple values fit (3,5,7,11,13,17,19), so the exact age cannot be determined.

5. What is the present age of Geeta's grandfather? I. Geeta's grandfather is older than her father. II. Geeta's father is older than Geeta.

AStatement I alone is sufficient, but Statement II alone is not sufficient
BStatement II alone is sufficient, but Statement I alone is not sufficient
CBoth statements I and II together are sufficient, but neither alone is sufficient
DBoth statements I and II together are not sufficient

Show answer

Answer: D

Both statements only establish a relative order of ages without any numerical values, so the grandfather's exact age cannot be found even combined.
