Question

If apples are bought at 11 for RS 10 & sold at 10 for RS 11, how much
will be the gain %?

Answer 1

Answer:

Gain % = 21%

Step-by-step explanation:

(when we are buying)

Price of 11 apples = Rs10

Price of 1 apple = Rs10/11(COST PRICE)

(when we are selling)

Price of 10 apples = Rs11

Price of 1 apple = Rs11/10(SELLING PRICE)

Gain = (SP - CP)

       =Rs(11/10-10/11)

       =Rs(21/110)

Gain % = Gain*100/CP

           = 21/110 * 11/10 * 1/100

           =21%
