Solution(By Apex Team)

Let the cost price be Rs. 100
then the mark up price which is 30% above the cost price,
Mark price = (100 + 30% of 100) = Rs. 130
Shopkeeper gives a discount of 10% on mark up price, then the
Selling Price = (130 – 10% of 130) = Rs. 117
Gain = 117 – 100 = Rs. 17
$\text{%gain }=\frac{17\times100}{100}=17\%$

**Short Cut method:**100(CP) == 30%↑ ⇒ 130(MP) == 10%↓ ⇒ 117(SP) Gain = 17%## Related Questions on Profit and Loss
