**Time Speed and Distance **

There is an escalator going up from the ground floor to the first floor. Varsha is climbing up the escalator while Sumit is climbing down (from the first floor to the ground floor) on the same escalator. On a stationary escalator, the time taken by Sumit to climb 8 steps is same as the time taken by Varsha to climb 6 steps. On the moving escalator, if Varsha takes 18 steps to reach the first floor while Sumit takes 60 steps to reach the ground floor, how many steps are there on the escalator?
