The marked price of an object is Rs 960. The shopkeeper allows a discount of 10 % and still gains 8 %. If no discount is given, his profit % would be:
1). 15
2). 18
3). 20
4). 22
We have MP = Rs 960
Discount = 10%
∴ SP = 960 – 10 % of Rs 960
= 960 – 96
= Rs864
$(\begin{array}{l} {\rm{CP}} = SP \times \frac{{100}}{{100 + p\% }}\\ \Rightarrow {\rm{CP}} = {\rm{}}864{\rm{}} \times {\rm{}}\frac{{100}}{{100 + 8}} \end{array})$
⇒ CP = Rs 800
If the product was sold for MP, profit = Rs 960 – Rs 800
= Rs 160
Profit % = $(\frac{{Profit}}{{CP}} \times 100)$
$(= \frac{{160}}{{800}} \times 100)$
= 20 %1. If selling price is doubled then, the profit triples. What is profit per cent?
