Answer 1

Answer:

Ratio of selling price and Cost Price,

SP : CP = 12 : 9 =4 : 3

Profit of 3 oranges = Rs. 1 (Let CP = Rs. 1)

Profit = 13

= 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.

Step-by-step explanation:

12 C.P = 9 S.P,

So profit % = 12C.P.−9C.P.9C.P.

= 33.33.

Then it is said that,

5 SP - 5 CP = 10 MP -10 SP

From that we get relation between MP and SP, that is,

27 SP = 24 MP(With help of 12 CP = 9 SP)

THEN DISCOUNT % = MP−SPMP

= 11.11%

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