Answer»

We have,

Time taken by the FIRST tap to fill the CISTERN =4 hours.

Time taken by the second tap to fill the cistern =3 hours

Work done by the first tap in 1 hour =41

Work done by the second tap in 1 hour =31

Thus, work done by both the TAPS in 1 hour =41+31=123+4=127

Both the taps together will fill the cistern in 712 hours.
