Answer 2

Answer:

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

%gain=17×100100=17%

%gain=17×100100=17%

Short Cut method:

100(CP) == 30%↑ ⇒ 130(MP) == 10%↓ ⇒ 117(SP)

Gain = 17%
