We know that Work done = m * g * h (h = 10 * 6 = 60m)

Power = Work/Time
= 240000/10
= 24000 KW.

tanisharaj:
why u have done 10*6 as, here it is not written that height of 1 floor is 6m
here 6m/hr is written.
In the question it is given 6m
Given total floors are 10 and height in each floor is 6m. So height of all floor becomes 10 * 6 = 60.
it can be by mistake but it is 6m/hr
Ohkkkk...Could u tell me the correct answer?
315.28horse power
