Detailed Solution

Concept- Using simple concepts of fraction in mathematics and applying them to multiply the amount obtained for one litre with the given quantity of the petrol.
It is given that the petrol pump delivers

4 \frac{2}{5}

litres

petrol in one minute.
We have to fill the tank with

16 \frac{1}{4}

litres

of petrol.
We get,

4 \frac{2}{5} = \frac{22}{5}

Similarly,

16 \frac{1}{4} = \frac{65}{4}

Therefore, we have given that the pump delivers

\frac{22}{5}

litres

petrol in one minute.
Therefore, time taken by the pump to deliver one

litre

of petrol is:

\frac{1}{\frac{22}{5}} = \frac{5}{22}

Therefore, the time taken by the pump to deliver one litre of petrol is

\frac{5}{22}

minutes.
Hence, to deliver 654654 litres of petrol the time taken is:

\frac{5}{22} \times \frac{65}{4} = \frac{3.69522 \times 65}{4}

Thus, time taken by the pump to deliver

\frac{65}{4}

litres of petrol is 3.69 minutes.
Hence, the correct option is 2.
