Show the answer and the worked solution
Correct answer: C. ₹18,000
Worked solution
- Each van uses 150 ÷ 10 = 15 litres a day.
- Fleet usage = 12 × 15 = 180 litres.
- Cost = 180 × 100 = ₹18,000.
Answer: ₹18,000.
The idea
Work through the chain one unit at a time: kilometres to litres, litres to rupees. Skipping a step is where errors enter.
Shortcut. Fuel costs ₹10 a kilometre (₹100 ÷ 10 km); the fleet drives 12 × 150 = 1,800 km, so ₹18,000.
Common trap. ₹15,000 — it echoes the 15 litres a van, but it is the cost of 10 vans, not 12; 15 litres × ₹100 × 12 = ₹18,000.
