Shyam and Vyom walk up an escalator (moving stairway). The escalator moves at a constant speed. Shyam takes three steps for every two steps of Vyom. Shyam gets to the top of the escalator after taking 25 steps, while Vyom takes only 20 steps to reach the top. If the escalator was turned off, then how many steps would they have to take to walk up to the top?
