Question

Ipsa bought a car which covers 363 km in 24.2 litres of petrol. What will be the distance covered using 7 litres of petrol?

• A. 213 km
• B. 105 km
• C. 67 km
• D. 86 km

Answer 1

The correct option is B

105 km

Let the required distance be y.

$\begin{array}{ccc}Distance\left(inkm\right)& 363& y\\ Amountofpetrol\left(inl\right)& 24.2& 7\end{array}$

The distance travelled and the amount of petrol consumed are directly proportional

$\frac{A}{B}$= Constant

$\frac{A_1}{B_1}$ = $\frac{A_2}{B_2}$

$\frac{24.2}{363}$ = $\frac{7}{y}$

$24.2\times y=363\times 7$

$y=\frac{7\times 363}{24.2}=105$ km
