All the above answers are wrong.
1. While going down he takes 50 steps and escalator moves x
steps down
50+x ....(1)
2. 5 times faster while going up, 50*5=250 and still the
escalator moves x steps down. so 250-x (2)
Equating both the equns
50+x = 250-x
x=100
use the x in any of the equation, that is the total number
of steps in the escalator.
When the person goes down 50 steps, escalator goes 100 steps
down. So total number of steps in that escalator is 150.
Period.
