4.

How much time did X take to reach the destination?

I. 

The ratio between the speed of X and Y is 3 : 4.

 II. 

Y takes 36 minutes to reach the same destination.

I alone sufficient while II alone not sufficient to answer
II alone sufficient while I alone not sufficient to answer
Either I or II alone sufficient to answer
Both I and II are not sufficient to answer
Both I and II are necessary to answer
Answer: Option
Explanation:

Since ratio of speed of X : Y is 3 : 4, then ratio of time will be 4 : 3.

 I. If Y takes 3 min, then X takes 4 min.

II. If Y takes 36 min, then X takes 4 x 36 min = 48 min.
3

Thus, I and II together give the answer.

Correct answer is (E).
