Three pumps working 8 hours a day can empty a tank in 2 days.How many hours a day must 4 pumps work to empty the tank in 1 day

Answer 1

Hey guys here is your answer!!!☺️


===========================

✔✔Let the required no. of working hours per day be 'x'

More no. of pump take less working hours per days

Less pump more working hours per days

Let the days , Pump and hours in the ratio...


Pumps 4 : 3...........(1)

Days 1 : 2.............(2)

and hours x : 8...........(3)


Multiply (1) , (2) and (3)


=> 4 × 1 × x = 3 × 2 × 8

=> 4x = 48

=> x = 48/4

=> x = 12


✔✔Therefore the pumps take 12 hours per day to complete the work in 1 days .....
