The price of petrol is raised to Rs.96.5 per litre from Rs.92 per litre. What is the percentage increase in price of petrol?

Correct option is C

Given:
The initial price of petrol = Rs. 92 per litre
New price of petrol = Rs. 96.5 per litre
Formula Used:
 $$\text{Percentage Change} = \left( \frac{\text{New Value} - \text{Initial Value}}{\text{Initial Value}} \right) \times 100$$​​
Solution:
Percentage increase = $$\left( \frac{96.5 - 92}{92} \right) \times 100 = \left( \frac{4.5}{92} \right) \times 100 = 4.9\%$$​​
