Answer Posted / pavan reddy s
Let escalator take n steps/sec.
So while moving down if man takes 50 sec for 50 steps, total steps are (50n+50).
While moving up for 125 steps he takes 25 sec(As speed is 5 times more now) so total steps are (25n+125).
Now in both cases equate the steps.
50n+50=25n+125
n=3
Sub in any of two cases total steps will be 200.
Ans: 200 steps.
