Detailed Solution
Download Solution PDFGiven:
Petrol poured = 50 litres
Tank is 10% empty.
Formula used:
Total capacity of the tank = Petrol poured ÷ (1 - % filled)
Petrol to be added = Total capacity - Petrol already poured
Calculation:
Total capacity = 50 ÷ (1 - 0.10)
⇒ Total capacity = 50 ÷ 0.90
⇒ Total capacity = 55.56 litres
∴ The correct answer is option (3).
