Question: What is Gagan's age ?

Statements:

  1. Gagan, Vimal and Kunal are all of the same age.
  2. Total age of Vimal, Kunal and Anil is 32 years and Anil is as old as Vimal and Kunal together.

[A]. I alone is sufficient while II alone is not sufficient
[B]. II alone is sufficient while I alone is not sufficient
[C]. Either I or II is sufficient
[D]. Neither I nor II is sufficient
[E]. Both I and II are sufficient

Answer: Option E

Explanation:

As given in I and II, we have: G = V = K, V + K + A = 32 and A = V + K.

Putting V + K = A in V + K + A = 32, we have: 2A = 32 or A = 16.

Thus, V + K = 16 and V = K. So, V = K = 8. Thus, G = 8.
