Question

3 'A' buys a radio at th of its marked price and sells it at 20% more than the marked price. What is A's gain percent?​

Answer 1

Answer:

Step-by-step explanation:

Let marked price be Rs.x

S.P=Rs.x+20%=Rs.x+20/100

Gain=S.P-C.P

x+20/100-x

120x/100-x=20x/100=x/5

Gain=x/5

Gain%=G/C.P of 100%

x/5/x of 100%

(x/5 of 1/x)×100%

x/5x×100%

x and x cancel

1/5×100%

20%
