Q)
anuj and agraj walk up an escalator,
which moves up at a constant speed .
anuj climbs 5 steps for every 3 that
agraj climbs. anuj gets to the top
of the escalator in twenty-five steps,
while agraj(his slower pace lets the
escalator do a little more work)takes
only 18 steps to reach the top. in how
many steps would anuj reach the bottom
from top,on same escalator if he doubles
his speed while returning
a)20 b)200 c)10 d)100
