A man can row downstream at 18 kmph and upstream at 10 kmph. Find the speed of the man in still water and the speed of stream respectively?

A. 13, 3
B. 12, 6
C. 15, 3
D. 14, 4

Explanation:

Let the speed of the man in still water and speed of stream be x kmph and y kmph respectively.

Given x + y = 18 — (1)
and x – y = 10 — (2)
From (1) & (2) 2x = 28 => x = 14, y = 4.

Correct Answer: 14, 4 ✔
