Question

the cash difference between selling a shirt at a profit of 10% and of 15% is rupees 10 . what are the two selling prices??​

Answer 1

Answer:

let cost price = x

two selling prices are  x(110/100)  and  x(115/100)

ATQ,

        x(115/100) -  x(110/100)  =  10

    ⇒ 5x = 10 × 100         ⇒ x = 200

    two selling prices are  200(110/100) =220

                                   and  200(115/100) =230
