Answer 1

Given:

Price of fuel at the end of March = ₹90 per litre

The bar graph shows the monthly percentage increase in fuel prices.

Percentage increase in April = 14%

Percentage increase in May = 12%

Calculation:

Price of fuel at the end of April = Price at the end of March + (Percentage increase in April × Price at the end of March)

Price at the end of April = 90 + (14/100) × 90

Price at the end of April = 90 + 0.14 × 90

Price at the end of April = 90 + 12.6

Price at the end of April = ₹102.6 per litre

Price of fuel at the end of May = Price at the end of April + (Percentage increase in May × Price at the end of April)

Price at the end of May = 102.6 + (12/100) × 102.6

Price at the end of May = 102.6 + 0.12 × 102.6

Price at the end of May = 102.6 + 12.312

Price at the end of May = ₹114.912 per litre

Increase in the price of fuel by the end of May compared to the end of March = Price at the end of May - Price at the end of March

Increase = 114.912 - 90

Increase = ₹24.912 ≈ 25

The price of fuel increased by approximately ₹25 by the end of May compared to the end of March.
