Answer»

tank filled by both tap in 4 minute= 1

tank filled by both tap in one minute= 1/4

tank filled by one tap in 7 minute= 1

tank filled by one tap in 1 minute = 1/7

let tank filled by other tank in 1 minute be x

1/7 +x = 1/4

x = 1/4 - 1/7

x = 7/28 - 4/28

x = 3/28

tank filled by other tap in one minute = 3/28

3/28 tank is filled by tap in =1 min

1 tank is filled by tap in = 28/3. min

28/3 minutes is the right answer
