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?

According to the question
The cost price of 12 oranges = The sale price of 9 oranges
So profit% = (12 C.P. - 9 C.P.)/9 C.P × 100 = 33.33%

Then it is said that,
5 S.P. - 5 C.P. = 10 M.P. -10 S.P.
From that
we get the relation between M.P. and S.P., that is,
27 S.P. = 24 M.P.(With help of 12 C.P. = 9 S.P.)
Then Discount%
= M.P. - S.P./M.P
= (27 M.P. - 24 M.P.)/27 M.P × 100
= 11.11%
So, % point discount
= 33.33% - 11.11%
= 22.22%
