Question

a dealer gains 7% by selling a mobile phone set for Rs 3852 find his gain percent if he sells it for Rs 4050

Answer 1

gain %= selling price/cost price * 100

7= 3852/cp *100 .... eq 1

let gain % be x if he sells it for 4050

x= 4050/cp *100 ... eq 2

dividing eq 2 by 1

x=  4050 * 7/ 3852

x= 28350/3852 = 7.36%
