Question

a refrigera is marked 30% above the cost price and the dealer allows a discount of 15% on it find his gain or loss per cent​

Answer 1

Answer:

Step-by-step explanation:

Let the C.P be X.

Then marked price = x+30%of x

= x+3x/10

= 13x/10

Discount = 15%

Selling price =

13x/10 - 15% of 13x/10

13x/10 - 39x/200

260x/200 - 39x/200

221x/200

Gain = S.P - C.P.

= 221x/200 - x

= 21x/200

Gain % = Gain*100/C.P

Gain % = 21x*100/200/x

Gain % = 10.5%
