Q1:
A man takes twice as long to row a distance against the stream as to row the same distance in favour of the stream. The ratio of the speed of the boat (in still water) and the stream is:
A
2 : 1
B
4 : 3
C
3 : 2
D
3 : 1
ANS:B -
3 : 1
Let man's rate upstream be x kmph.
Then, his rate downstream = 2x kmph.
(Speed in still water) : (Speed of stream) =
