I.  Rahul got one-fourth of the profit.
 II.  Rahul and Vivek contributed 75% of the total investment.

A I alone sufficient while II alone not sufficient to answer

B II alone sufficient while I alone not sufficient to answer

C Either I or II alone sufficient to answer

D Both I and II are not sufficient to answer

E Both I and II are necessary to answer

ANS:E - Both I and II are necessary to answer

Let the total investment be Rs. x.

Then, R = x
4
R + V = 75 x = 3x
100 4
V = 3x - x = x .
4 4 2
 A = x - x + x = x
4 2 4
R : A : V = x : x : x = 1 : 1 : 2.
4 4 2
Thus, both I and II are needed to get the answer.  Correct answer is (E).
