Aryan bought a car for Rs. 3,50,000. The next year, the price went up to Rs. 3,70,000. What was the percentage of the price increase?

Given: Initial price of the car = Rs. 3,50,000

Increased price of the car = Rs. 3,70,000

Increase in price of the car = 3,70,000 − 3,50,000 = Rs. 20,000

∴ Percentage increase in price

$=\left(\frac{\mathrm{Increase} \mathrm{in} \mathrm{price}}{\mathrm{Initial} \mathrm{price}}\right)\times 100$

$=\left(\frac{20,000}{3,50,000}\right)\times 100$

$=\frac{200}{35}$

$=5.7\%$

Therefore, the percentage increase in the price of the car is 5.7%.
