b) 22.22
c) 16.66
d) 15
Answer: b
Explanation: Ratio of selling price and Cost Price,
SP : CP = 12 : 9 =4 : 3
Profit of 3 oranges = Rs. 1 (Let CP = Rs. 1)
Profit = $$\frac{1}{3}$$ = 33.33%
Discount = 11.11%
CP : SP : MP = 3 : 4 : 4.5
Profit doubles that of discount.
So, % point discount = 33.33% – 11.11% = 22.22% point.
