Total time taken to fill the tank by 1 pipe = 6 hours
Tank will be half filled in = 6 * 1/2 = 6/2 = 3 hours
Part remaining = 1/2
Time to fill another 1/2 is 3 hours by 1 pipe
Time taken by 4 pipes together to fill the tank = 3/4 = 45 mins
The tank will be filled in 45 mins.

Time taken to fill half of tank = 3hours
Time taken to fill the tank = 6 hours
Rate of filling water by one pump = 1/6
Rate of filling water by 4 pump = 4×1/6
= 2/3
Time taken to fill another half
= 1/2 ÷ 2/3
= 3/4 hours
= 45 minutes
Time taken to fill the tank = 6 hours
Rate of filling water by one pump = 1/6
Rate of filling water by 4 pump = 4×1/6
= 2/3
Time taken to fill another half
= 1/2 ÷ 2/3
= 3/4 hours
= 45 minutes
