Let the second pipe can fill tank in x hours So, first pipe fill tank in x-10 hours and Third pipe fill tank in x 10 hours According to the question, Second pipe and third pipe together take 2 hour more time to fill the tank from first pipe. So time taken by second pipe third pipe together x 10 2 hours x 8 hours 1x 1x 10 1x -8 x 10 x x2 10 x 1x - 8 x 8 2x 10 x2 10x 2x2 10x - 16x 80 x2 10x x2 - 16x 80 0 x2 - 20x 4x 80 0 xx 20 4x 20 0 x 20 x 4 0 x - 4, 20 So second pipe can fill the tank in 20 hours alone.
