Solution

Given selling price, SP=24

Dealer gains as much percent as the cost price of the article.

Let cost price be x

So, Gain%=x

We know that,

Gain%=(SPCP)×100CPx=(24-x)×100xx2+100x-2400=0x2+120x-20x-2400=0x(x+120)-20(x+120)=0(x+120)(x-20)=0x=-120orx=20

We neglect x=-120 since the cost price cannot be negative.

Sox=20

Hence the cost price of the toy is 20.
