time taken by man on moving escalator = 120/5 = 24
time taken by escalator = 120/3 = 40
steps taken by man per unit time = 120/24 = 5
steps taken by man when escalator is moving per unit time = 120/40 = 3
Total steps taken per unit time = 3+5 = 8
Total time taken = 120/8 = 15
total time taken in round trip = 15× 2 = 30
time taken by escalator = 120/3 = 40
steps taken by man per unit time = 120/24 = 5
steps taken by man when escalator is moving per unit time = 120/40 = 3
Total steps taken per unit time = 3+5 = 8
Total time taken = 120/8 = 15
total time taken in round trip = 15× 2 = 30
