- 1. Multiple Choice
m = 3x + y n = 3x - y
m = 1/ (3x + y) n = 1 / ( 3x - y)
m = 1 / (x + y) n = 1 / (x - y)
m = 1/ 2(x + y) n = 1/ 2(x - y)

During lockdown, Amar and Birju decided to walk to their village 30 kms away. Amar took 3 hours more than Birju to reach the village. However,if Amar had walked twice as fast he would have reached 3/2 hours before Birju. Find their speed of walking.
Amar's speed = 10 kmph Birju's speed = 0 kmph
Amar's speed = 10/3 kmph Birju's speed = 5 kmph
Amar's speed = 3/10 kmph Birju's speed = 1/5 kmph
None of the above

A boat takes 6 hours to travel 24 km upstream and 28 km downstream but it takes 6 hours and 30 mins to travel 30 km upstream and 21 km downstream. Find the speed of the boat in still water and speed of the stream.
Speed of boat in still water = 10 kmph Speed of stream = 4 kmph
Speed of boat in still water = 10 kmph Speed of stream = ─ 4 kmph
Speed of boat in still water = 1/ 6 kmph Speed of stream =1/14 kmph
None of the above
