Answer & Explanation Answer: D) If the data in both the statements together are needed.

Explanation:

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

Putting V + K = A in second. we get 2A = 32 or A = 16.

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

Hence, both the statements are needed.
