A man can row 24 kmph in still water. It takes him thrice as long to row up as to row down the river. Find the rate of the stream?

A.1 kmph
B.2 kmph
C.12 kmph
D.22 kmph
Answer and Feedback
Answer:C
Feedback:Let man's rate upsteam be X kmph
Then his rate of downstream = 3X kmph
Rate still water = 1/2 (3X + X) = 2X
2X = 24
X = 12
Rate of upstream = 12
Rate of downstream = 36
Rate of stream 1/2 ( 36 - 12) = 12 kmph
