x and y walk up the escalator (moving stairway). The escalator moves at a constant speed. x takes 3 steps for every y's steps. x gets to the top of the escalator after having takes 25 steps, while y(because his lower pace lets the escalator do a little more of the akes only 20 steps to reach the top. if the escalator were turned off,how many steps would they have to walk up?
Options hai kya ?
3x, x are the speeds
25 + (25/3x)*u = 20 + (20/x)* u
Yaar, iska answer fraction me aa raha hai ... ... u = 3x/7
=> N = 25 + 25/7 = 200/7 ... !
Kya galti kar raha hu main Waise bhi escalator hai.. Abhi tak ek bhi slot me escalator ka question aaya hai kya ?
