Question

Two large and 1 small pumps can fill a swimming pool in 4 hours. One large and 3 small pumps can also fill the same swimming pool in 4 hours. How many hours will it take 4 large and 4 small pumps to fill the swimming pool.(We assume that all large pumps are similar and all small pumps are also similar.)

She's good with math, she'll be able to explain it whenever she gets the chance :P

Answer 6

Ok thanks

Answer 7

Let the capacity of a big pump be x and the capacity of a small pump be y,
Now, if in both cases, the time taken is 4 hours, their combined capacity of the pumps are equal, as the volume of the pool is constant and the time taken is same

Answer 8

2x+y=x+3y

Answer 9

with equals x=2y

Answer 10

do u know how many hours

Answer 11

Yep, but direct answers are not allowed. So I am explaining it :D

Answer 12

Now, the volume of the pool remains constant whatsoever.
And, Volume of pool=Capacity of pumps*Time taken
Let the time taken by the 4 large and 4 small pumps be t,
Now, we will equate the volume of the pool
