Answer:

The time taken by 12 taps is 5 minutes.

Step-by-step explanation:

Given :

4 taps fill the tank in 15 minutes

To find :

Time required to fill the tank using 12 Taps

Solution :

Let the time taken by 12 taps be m

\begin{tabular}{|c|c|c|}\cline{1-3}\ Time (x) & 15 & m \\\cline{1-3}\ Taps required (y) & 4 & 12 \\\cline{1-3}\end{tabular}

Indirect Variation :

\bigstar \: {\boxed{\sf{x \times y = k}}}

\sf{\implies} \:4 \times 15 = 12 \times m \\  \\  \sf{\implies} \: 60 = 12m \\  \\ \sf{\implies} \: m =  \dfrac{60}{12}  \\  \\ \sf{\implies} \: m = 5

Time taken = 5 minutes

\therefore The time taken by 12 taps is 5 minutes.
