1.  Cost price of 12 oranges is equal to the selling price of 9 oranges and the discount on 10 oranges is equal to the profit on 5 oranges. What is the percentage point difference between the profit percentage and discount percentage?
A. 20
B. 22.22
C. 16.66
D. 15

Answer: Option B

Explanation:

Ratio of selling price and Cost Price,

SP : CP = 12 : 9 = 4 : 3

Profit of 3 oranges = Re 1 (Let CP = Re 1)

Profit = 1/3 = 33.33%

And, Discount = 11.11%

Since, CP : SP : MP = 3 : 4 : 4.5

Profit doubles that of discount.

So, % point discount = 33.33% -11.11% = 22.22% point.
