THANKS FOR QUESTION

YOUR ANSWER IS

Assume the cost of article is x

the person sold at 20% loss

Loss % =

C.P

C.P−S.P

=

x

x−S.P

=

100

20

∴ S.P =0.8 x

If he had sold it for Rs. 12 more, then he would have gained 10%.

Gain % =

C.P

S.P−C.P

=

x

(0.8x+12)−x

=

100

10

∴12−0.2x=0.1x

∴12=0.3x

∴x=40
