A pipe can fill a tank in 12 min
This means , in 1 min 1/12 part of tank is filled.
Another pipe can fill the tank is 15 min.
Which means in 1 min 1/15 part of tank is filled.
So if both the pipes are kept open , (1/12 +1/15) part of work is done in 1 min.
After this refer to the image attached . Thanks.
