Question

Solve the following .
A tractor uses up 12 litres of diesel while ploughing 3 acres of land. How much diesel will be needed to plough 19 acres of land?

Answer 1

Amount of diesel used by tractor to plough 3 acres of land = 12 litres

∴ Amount of diesel used by tractor to plough 1 acre of land = $\frac{12}{3}$ = 4 litres

⇒ Amount of diesel used by tractor to plough 19 acres of land = 4 × 19 = 76 litres

Thus, the amount of diesel needed to plough 19 acres of land is 76 litres.
