Answer Posted / sabih
if we consider the length of the train to be x meters and the speed of the train be ykm/h then the time taken by the train to cross the electric pole =x/y which equals 15(given).now as we proceed ,we know that the length of the platform is 100 meters so,
100+x/25=x/15
15(x+100)=25x
15x+1500=25x
15x-25x=1500
-10x=1500
x=-150 meters,
which we can consider as 150 meters.
