Answer 1

Answer:

Rs20

Step-by-step explanation:

sp of toy=Rs 24.

let the CP of the toy be Rs x

therefore,gain%=

$\frac{sp - cp}{cp} \times 100$

=X=24-x/x ×100

=x²+100x-2400=0

=x²+120x-20x-2400=0

=(X+120)(x-20)=0

therefore,

X+120=0 or x-20=0

=X=120 or X=20

as cost can't have a negetive value,

therefore, cost price=X=Rs20
