Question

9. A trader allows a discount of 13% on the marked price. How much above the cost price must he mark his goods to make a profit of 19%? a​

Answer 1

Answer:

Step-by-step explanation:

Let the marked price be decided to be x% above the cost price, then

6.6 = x – 18 – 18x/100

⇒ 6.6 + 18 = x – 0.18x

⇒ 0.82x = 24.6

⇒ x = 24.6/0.82 = 30

Detailed Method:

Let the Cost price of the article be Rs. 100, then

SP of the article = 100 × (106.6) = Rs. 106.6

MP of the article = 106.6 × (100/82) = 130

MP is more than CP by = 130 – 100 = 30

∴ MP is more than CP by (in %) = 30/100 × 100 = 30%
