Question

(c)By selling an article for *270, a loss of 10 percent is suffered. Find: (i) the cost price of the article. (ii) the price at which the article must be sold in order to gain 12 %.​

Answer 1

Answer:

Given that ;

Selling price of an article ( SP ) = 270

Loss Percentage = 10 %

i ) CP of the article

Let

The CP of article be x

Loss = CP - SP

Loss = x - 270

Loss % = Loss / CP × 100

10 = x - 270 / x × 100

1 = x - 270 / x × 10

x = 10x - 2700

9x = 2700

x = 2700 / 9

x = 300

Cost Price of Article = 300

ii ) SP to gain 12%

Selling Price = 297
