A. 21%
B. 20%
C. 18%
D. 17%
Answer: Option D
Solution (By Examveda 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 $$\% {\text{gain}} = \frac{{17 \times 100}}{{100}} = 17\% $$ Short Cut method: 100(CP) == 30%↑ ⇒ 130(MP) == 10%↓ ⇒ 117(SP) Gain = 17%This Question Belongs to Arithmetic Ability >> Profit And Loss
A shopkeeper marks his goods in such way that after allowing a discount of 12.5%on Mark price he still makes a profit of 10%. If the cost price of good is 245, then find its marked price.
let solve this formula
let profit value +30
and discount or lose -10
x+y+xy/100
30-10-30*10/100 =17%
Let the cost price be Rs.100.
The marked price is 30% above the cost price.
So, the marked price will be Rs.130.
The discount is 10% and hence the selling price will be,
90% of 130 = 90/100 * 130 = Rs.117.
Gain = s.p - c.p = 117 - 100 = Rs.17
gain % = gain/c.p * 100 = 17/100 * 100 = 17%
