Question:
After allowing a discount of 8% on a toy, it is sold for Rs 216.20. Find the marked price of the toy.
Solution:
Selling Price $=$ Rs $216.20$
Rate of discount $=8 \%$
Marked Price =?
SP $=\mathrm{MP}-$ discount
Let the MP be Rs $x$.
Now, $x-\frac{8}{100} \times x=216.20$
$\Rightarrow \frac{92 x}{100}=216.20$
$\Rightarrow 92 x=21620$
$\Rightarrow x=\frac{21620}{92}$
$\Rightarrow x=235$
$\therefore$ Marked price $=R s 235$
