Shyama and Vyom walk up an escalator (moving stairway). The escalator moves at a constant speed. Shyama takes three steps for every two of Vyom's steps. Shyama gets to the top of the escalator after having taken $25$ steps. While Vyom (because his slower pace lets the escalator do a little more of the work) takes only $20$ steps to reach the top. If the escalator were turned off, how many steps would they have to take to walk up?

  1. $40$
  2. $50$
  3. $60$
  4. $80$
