Question

A dealer sold a radio at a loss of 2.5%.Had he sold it for 100/-more,he could have gained 7.5%

Answer 1

Step-by-step explanation:

let,C.P is x

then, sp at 2.5% loss=x*(97.5/100)

sold 100 more then sp=x*(107.5/100)

then,x*(97.5/100)+100=x*(107.5/100)

x*(107.5/100)-x*(97.5/100)=100

x/10=100

x=1000
