Given, power of pump = 2kW =2000W
Time (t)= 60sec
Height (h) = 10m
g = 10m/s2. (I have taken 10 for easy calculation as it wasn't given in the question)
As you know, power =work done per unit time.
Work done = mgh = m ×10×10 =100m
Therefore, 2000W = 100m/60s
Therefore, m = 1200kg
So, the pump can raise 1200kg of water in one minute.
hope it helps

Nice explanation!

YOUR ANS. IS NOT CORRECT
mine ans is also correct
i had taken g = 10 and you have taken g= 9.8. only that cause a difference
THE VALUE OF g = 9.8 only
in the question its not mentioned whether we have to take g as 9.8 only
and if you swipe through books u will find that for most of the question g is taken as 19
*10

Explanation:
Given,
Power (P)=2kW
=2000W
Time(t)=60sec
Height (h)=10
g=9.8
as we know,
Work done=10×9.8
=98J
therefore,2000=98m/60
so,m=1224.4898
=1224.5
