Answer 2

Given: 6 pumps working 5 hours a day, can empty a tank in 3 days.

To find: We have to find the number of hours required to empty the tank by working 10 pumps together in 1 day.

Solution:

To determine the number of hours required we have to use the below formula-

N1D1H1=N2D2H2

Where N1 is the initial number of pumps=6

D1 is the initial number of days required to complete the work=3

H1 is the initial working hours=5

N2 is the required number of pumps=10

D2 is the days required to complete the work=1

H2 is the working hours=x

Putting the values in the above formula we get-

$6 \times 5 \times 3 = 10 \times x \times 1 \\ x = 9$

9 hours must 10 pumps work to empty the tank in 1 day.
