One tap fills the cistern in 9 hours . The other tap fills the cistern in 6 hours .
: Work done by one tap in 1 hour = 1/9
Work done by other tap in 1 hour = 1/6
The work done by both taps in 1 hour
= 1/9 + 1/6
=Then we took lcm of 9 and 6 that is 18
: 2+3/18
= 5/18
: Both the taps when opened together will fill the cistern in 18/5 hours.
