Answer:
Time taken by the Frist tap to fill the cistern - 8 hours
Time taken by the second tap to fill the cistern- 4 hours
Therefore, work done by the Frist tap in 1 hour = 1/8
work done by the second taps in 1 hour = 1/8 +1/4
1+2/8 = 3/8 ,,,,
Thus,both the taps together will fill cistern in 8/3 hours or 2 2/8 hours
