Correct Answer: I, II and III together are not sufficient
Explanation:
The information given in the three statements together is also not sufficient to answer the given question.
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.
Correct Answer: If the data even in both the statements together are not sufficient to answer the question

Explanation:
The present price of the mixer can he calculated from statement II as follows
Let the earlier price be Rs x.
Then, 10% of x = 220 or x = 2200. Present price = Rs (2200 + 220) = Rs 2420.
So, only II is needed.
Correct Answer: If the data in both the statements together are needed.
Explanation:
