Let the cost price of 1 toy be x.
Then,cost price of 12 toys is 12x
A/Q
Selling price of 15 toys=cost price of 12 toys=12x
So,selling price of 1 toy=\frac{12x}{15}
15
12x
=\frac{12x÷3}{15÷3}
15÷3
12x÷3
=\frac{4x}{5}

4x
\begin{gathered}Loss=C.P.-S.P\\ =x - (\frac{4x}{5})\\ = \frac{5x}{5} - \frac{4x}{5} \\ =\frac{x}{5}\end{gathered}
Loss=C.P.−S.P
=x−(
