Question

The cost of petrol is ₹ 100. If the cost increases by 40%, then the new price is ₹ .

• A. 140
• B. 240
• C. 340

Answer 1

The correct option is A 140

When the price of petrol increases by 40%,
Revised price = Original price + 40% of original price
= Original price$\times$ $\frac{100+40}{100}$
= Original price$\times$ $\frac{140}{100}$
If original price = ₹ 100 for a certain quantity,

Revised price for the same quantity = 100 $\times$$\frac{140}{100}$ = ₹ 140.
