Question

9 taps can fill a tank in 4 hours. How many hours will it take to fill 12 taps

Answer 1

It is given that

9 taps can fill a tank in 4 hours

`\begin{gathered} \Rightarrow9t=4h \\ \Rightarrow12t=x \\ \\ \Rightarrow9t* x=12t*4h \\ \\ \Rightarrow x=(12t*4h)/(9t)=(12)/(9)*4=(16)/(3)h \end{gathered}`

Therefore, it will take 16/3 hours for it to fill 12 taps.
