  Infosys Puzzles 1. There is a escalator and 2 persons move down it.A takes 50 steps and B takes 75 steps whilethe escalator is moving down. Given that the time taken by A to take 1 step is equal to timetaken by B to take 3 steps. Find the no. of steps in the escalator while it is staionary. Solution (not sure) :If A takes 1 step in one second, then B takes 3 steps in one second. If A takes t1 seconds totake 50 steps, then B takes 150 steps in t1 seconds.For B, to take 150 steps he requires t1 seconds,then to take 75 steps he requires t1/2 seconds.So now, s1=50, t1 = t1 & s2=75, t2=t1/2ans= (s1*t2 ~ s2*t1) / (t1 ~ t2) which gives 100.so 100 steps is the answer2.
