Question

three pipes a b and c can fill a swimming pool in 6 hours after working on it together for two hours c is closed and A and B fill the remaining part in 7 hours find the number of hours taken by c alone to fill the swimming pool​

Answer 1

Answer:

Part filled in 2 hours = 2/6 = 1/3. Remaining part = 2/3

(A + B)'s 7 hours' work = 2/3.

So, (A+B)'s 1 hr work = 2/21

Therefore C's 1 hour's work

= [(A+B+C)'s 1 hour]-[(A+B)'s 1 hr work]

=(1/6 - 2/21) = 1/14

C alone can fill the pool in 14 hours
