Bobby and Arpit are climbing on a moving escalator that is going up. Bobby takes 30 steps to reach the top but Arpit takes 32 steps to reach the top. Bobby can take 3 steps in a second while Arpit can take 4 steps in a second. Calculate the total number of steps in the escalator.
Explanation:
No. of steps = 30 + (30/3)x (Since Bobby is moving in the same direction, 10x will be added)
No. of steps = 32 + (32/4)x (Since Arpit is moving in the same direction, 8x will be added)
On equating the number of steps,
30 + 10x = 32 + 8x
x = 1 step per second.
Number of steps = 30 + (10 × 1) = 40 steps.
Hence, 40.
