Question
5 out of 50
 

Two boys are playing on a ground. Both the boys are less than 10 years old. Age of the younger boy is equal to the cube root of the product of the age of the two boys. If we place the digit representing the age of the younger boy to the left of the digit representing the age of the elder boy, we get the age of the father of the younger boy. Similarly, if we place the digit representing the age of the elder boy to the left of the digit representing the age of the younger boy and divide the figure by 2, we get the age of the mother of the younger boy. The mother of the younger boy is younger to his father by 3 years. Then, what is the age of the younger boy?



A 3

B 4

C 2

D None of these

Ans. C

Only two combinations possible are:

Younger

Older

2

4

3

9

Cubes of natural numbers are 1, 8, 27, 64……. Here, 64 and above is not possible as the age will go above 10. Only B. and C. satisfy the case of mother and father.
