Me and my friend Riad coming down from 2nd floor to 1st floor through two escalator respectively(means we are using two different escalator but each of them have equal stair,they are also same in everything).i am in a bit of hurry,so i came down 3 stair at a time when my friend is steady and came 1 stair at a time.For this he had to pass 50 stair in all and i had to pass 75 stair(remember,the escalator was running/working then).If the escalator remain stopped,how many stair would there be????(escalator is a staircase which runs by itself)

What if one was going up and the other was going down?

it doesnt make sense that you are taking more steps at a time and pass more stairs than him... You're supposed to be faster therefore pass less stairs.
