Question

pens are bought at 12 for a Rupee and sold at 9 a Rupee find the gain percentage​

Answer 1

Answer:

33.3%

Step-by-step explanation:

Let the price of pens be "x" instead of one rupee.

Cost Price (C.P) of 12pens = 12x

Selling Price (S.P) of 9pens = 9x

C.P = S.P

12x = 9x

This can be written as,

S.P = C.P

12x = 9x

Gain = 12x - 9x = 3x

Gain% = Gain/C.P*100 = 3x/9x*100 = 33.33%
