Dear Student
Thank you for using Chegg !!
Given 3 pipes filling a tank
Let vlume of tank be V
Then rate of filling from Pipe A be V/7
Then rate of filling from Pipe B be V/8
Then rate of filling from Pipe C be V/28
If all 3 pipes are operation at a time then time taken for filling be T
T	=	V / ((V/7) + (V/8) + (V/28)
	=	1 / ((1/7) + (1/8) + (1/28))
	=	3.294118	hrs
