 D

if the data in both the statements I and II together are necessary to answer the question.

Soln.
Ans: d

Let x students score first class. Then by statement I, failed = 48 - 3x. And, by statement II, 48 - 3x = 3x, which gives x = 8.

Hence, I and II together are necessary to answer the question.
