Question

If the present price of diesel is ₹ 50, then what is the new price in ₹ when:

i) there is an increase of 20% on the original price?

ii) there is a decrease of 10% on the original price?

• A. 60, 45
• B. 75, 80
• C. 45, 60
• D. 80,75

Answer 1

The correct option is A

60, 45

i) When there is an increase of 20% in the price, the increase in price is:
= $\frac{20}{100}\times 50=10$
Therefore, the new price of diesel is: ₹ (50 + 10) = ₹ 60

ii) When there is a decrease of 10% in the price, the decrease in price is:
= $\frac{10}{100}\times 50=5$
Therefore, the new price of diesel is: ₹ (50 - 5) = ₹ 45
