volume of water in the tank is 100×50×20=100000cm^3
water was raised in 15sec=50cm
so the volume of water raised in 15sec=100×50×50=250000cm^3
250000 released in 15 sec then 100000
released in 15/250000 ×100000=15/2.5=6sec
water was raised in 15sec=50cm
so the volume of water raised in 15sec=100×50×50=250000cm^3
250000 released in 15 sec then 100000
released in 15/250000 ×100000=15/2.5=6sec
