Question:
A shop selling sewing machines offers 3% discount on all cash purchases. What cash amount does a customer pay for a sewing machine the price of which is marked as Rs 650.
Solution:
$D$ iscount $=3 \%$
Marked price $=$ Rs. 650
Now, $3 \%$ of the $\mathrm{MP}=\frac{3}{100} \times 650$
$=$ Rs $19.50$
So, SP $=$ MP $-$ Discount
$=650-19.50$
$=$ Rs $630.50$
