6pipecanfillatank=60+20=80min​5pipescanfillatank=xmin​​∵Itisininverseproportion​6×80=5×x​x=​5​​6×80​​​x=96min​​Hence,Timetakenby5pipetofilltank=​​96min​​​​​​​​

plz accept as best

6 pipes = 60min 20min = 80min

5 pipes = x min

6*80 = 5*x

x=480/5 =96min

Number of pipes and time taken are inversely proportional.

That is, if number of pipes decrease then the time increases and vice versa.

Time taken by 6 pipes to fill the tank = 1hour 20min = 60+20=80min

Let the time taken by 5 pipes by y

As they are inversely proportional,

6×80=5×y

6×80/5 = y

96min= y

Time taken by 5 pipes to fill the tank= 1hour and 36minutes
