@kaveri
1/5+1/6+-1/12=
L.C.M of 5,6,12=60
So 1/5+1/6-1/12
12+10-5
--------------= 17
60 --------
60
1/5+1/6+-1/12=
L.C.M of 5,6,12=60
So 1/5+1/6-1/12
12+10-5
--------------= 17
60 --------
60

@komal
net part in 1 hour is 17/60 part
so in 60/17 hour the part will be 1
here 1 means tank is full.....
its just like the time and wok concept...
