  • Options
  • A. If the data in statement I alone are sufficient to answer the question
  • B. If the data in statement II alone are sufficient answer the question
  • C. If the data either in I or II alone are sufficient to answer the question;
  • D. If the data in both the statements together are needed.

  • Correct Answer
  • 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.
