Set-1 : Boats & Stream
Directions (1 - 5): Read the following passage and answer the given questions
Day 1: A person covers 200 km along the stream and 150 km against the stream. The difference between the time
taken to cover upstream and downstream is 10 hours.
Day 2: A person covers 40 km less than the previous day in along the stream and distance covered against the stream
is equal to the distance covered by the same person in day 3 along the stream. Time taken to cover downstream
distance is 8 hours less than the upstream distance.
Day 3: Distance covered along the stream is 40 km more than the distance covered against the stream which is equal
to the distance covered by a person on day 1 along the stream. He takes 6 hours more to cover upstream than the
downstream distance.
Day 4: Time taken to covers 200 km along the stream and 100 km against the stream is same as the total time taken
by the same person on day 3.
The speed of stream on day 1, 2, 3 and 4 is 15kmph, 10 kmph, 20 kmph and 20 kmph respectively.
