प्रश्न
A truck uses 20 litres of diesel for 240 km. How many litres will be needed for 1200 km?
उत्तर
litres of diesel used for 1 km.
240 km & 20 litres
1 km = `20/240` litres
= 0.0833 litres
litres of diesel used for 1200 km.
1 km = 0.0833 litres
1200 km = 0.0833 × 1200 litres
= 99.96
≈ 100 litres
100 litres of diesel is required for 1200 km.
