Question

The distance covered by a boat while moving in downstream in a fixed time is 3/4 more than in upstream. The speed of stream is what % of the still water speed of boat?

A (11.11)% Correct Answer Incorrect Answer
B (27.27)% Correct Answer Incorrect Answer
C (13.13)% Correct Answer Incorrect Answer
D (17.17)% Correct Answer Incorrect Answer
E none of these Correct Answer Incorrect Answer

Solution

As we can conclude that time is given constant, distance ∝ speed (v + u) / (v − u) = 175/100 (v) / (u) = 11/3 Required % = 3/11 x 100 = (27.27)%
