Step-by-step explanation:

Cost price of radio is equal to marked price

selling price is 20% more than marked price.

TO FIND

Profit(gain) percentage= ?

FORMULA

Profit= sp-cp

and profit % =profit/cp × 100%

SOLUTION

Let the marked price of radio=x

then,cost price of radio(c.p)= x

selling price of radio(s.p)= x+20% of x [by quest

= x+(20×x)/100

= x+x/5

=(5x+x)/5

=6x/5

therefore,profit= sp-cp

=6x/5 -x

=(6x-5x)/5

=x/5

profit%= profit/cp × 100%

=(x/5)/x ×100%

=(x ×100%)/5x

= 20%
