Expert Answer
The question should be like below
If a person climbs up 5 stairs every second and climbs down 2 stairs over next second. How many seconds will he take to climb 60 stairs
5 steps in one second
-2 steps in 2 seconds i.e. 3 steps
Therefore, 3 steps in 2 seconds
60 sec = 60/3 = 20
20 X no. of sec per 3 steps (2)
= 40 seconds
-2 steps in 2 seconds i.e. 3 steps

60 sec = 60/3 = 20
