3 taps fill a tank in 40 hours. how long would it take 20 taps to fill this tank?

Question

plz put the method to solve it...

Answer 1

Dreamer is correct, it would take 6 hours.  Why would it take longer to fill it using more taps? The other answers are incorrect.  If you divide 20 by 3 (those are the number of taps used) you get 6 2/3. Then divide 40 hours by that number (6.6666666667) and thats how you get your number of hours.

20/3=40/x

Answer 2

well, this means that each tap would fill it in 3 times 40, which is 120, so 20 taps would fill it 20 times faster, which would be 6 hours..(120/20 make 6, that is)

this is because the more taps there are, the faster it would fill

btw, Berry:

x hrs = (40 hrs x 3 taps)/20 taps = 13.33 hrs????????

40 x 3/20 = 120/20 = 6hours..

Answer 3

I is by unitary method ...i.e make 2 columns firstly write no. of taps in 1 n hrs in the other

its like this

taps                           hrs

3                                    40

1                                     40/3

20                                      20*40/3

hope this helped u n the ans is 133.2 hrs

Answer 4

3 taps in 40 hrs

20 taps in x hrs

the number of taps and the time required to fill the tank are inversely related. So,

20 taps/3 taps = 40 hrs/x hrs

x hrs = (40 hrs x 3 taps)/20 taps = 13.33 hrs

Sorry yeah that was a calculating problem. Funny how I got that answer. But my method is correct ;)

Yes, (40 hrs x 3 taps)/20 taps = 6 :))
