Question

4. By selling 100 toys, a dealer gains the selling price of 20 toys. Find his gain percent.​

Answer 1

Answer:

S.P. of 100 pencils − C.P. of 100 pencils = S.P. of 20 pencils

⇒ S.P. of 80 pencils = C.P. of 100 pencils

Let C.P. of 1 pencil = Rs. 1

Then S.P. of 80 pencils = Rs. 100

⇒ C.P. of 80 pencils = Rs. 80

∴ Profit % =

80

100−80

×100=

80

×100=25%
