Book Maths Puzzle Numerical Ability

River is running at 2 kmph. It takes a man twice as long to row up as to row down the river. The rate of the man in still water is
a )6 kmph b) 4 kmph
c) 10kmph d) 8 kmph

Read Solution (Total 1)

a) 6 kmph

If rate/speed of the man in still water=x kmph and distance=d, then
Time taken to row up the river=d/(x-2) & down the river=d/(x+2)
Given d/(x-2) = 2d/(x+2), x=6
