Detailed Solution
Download Solution PDFGIVEN :
If the price of petrol has increased from Rs. 40 per litre to Rs. 60 per litre
CALCULATION :
Let the consumption be 100 litres.
When price is Rs. 40 per litres, then, the expenditure = 100 × 40
⇒ Rs. 4,000.
At Rs. 60 per litre, the 60 × consumption = 4000
Consumption = 4,000/60 = 66.67 litres.
∴ Required decreased % = 100 - 66.67 = 33.33%
