Question

State whether the given statement is true or false:

A 10% hike in petrol price between yesterday and today means that a man who paid ₹ 200 for some petrol yesterday, will pay ₹ 220 for the same amount of petrol today.

• A. True
• B. False

Answer 1

The correct option is A

True

When the price of petrol increases by 10%,

Revised price = Original price + 10% of original price

= Original price $\times \frac{110}{100}$

Hence Revised Price = Original price $\times (1+\frac{10}{100}$)

= Original price $\times \frac{110}{100}$

If original price = ₹ 200 for a certain quantity,

Revised price for the same quantity = $\frac{110}{100}\times 200$ = ₹ 220.
