• A. 40%
• B. 50%
• C. 60%
• D. 80%

Answer 1

The correct option is C

60%

The cost of 12 oranges last year = ₹ 72 The cost of 1 orange last year = $\frac{72}{12}$ = ₹ 6 The cost of 20 oranges this year = ₹ 48 The cost of 1 orange this year = $\frac{48}{20}$ = ₹ 2.4 Difference in price per orange = ₹ 6 - ₹ 2.4 = ₹ 3.6 $\therefore$ Percentage change = $\frac{3.6}{6}\times$100 = 60%
