Question

Find the cost price of an article which is sold at Rs 630 at a profit of 12.5%

Answer 1

Given,

Sold  Price = R.s. 630

Profit = 12.5 %

Let the cost  price  of the article  be R.s x

We know  that  % of profit  is  measured with respect  to cost price

Hence,

Profit = 12.5% of cost  price

         = x × 12.5/100

         = R.s 0.125x

Again,

Sold Price = cost  price + profit

630 = x + 0.125x

630 = 1.125x

x = 630/1.125

x =  560

Cost  price  of  article  = R.s. 560

$<b><i><u>Selling$ Price = ₹ 630

Let price of cost price be x

PROFIT = 12.5 % of cost price

= 12.5 / 100 * x

= 12.5 x / 100

= 0.125 x

According to Question :-

x + 0.125 x / 100 = 630

1.125 x = 630

x = 630 / 1.125

x = 560

Hence ,

Cost Price = ₹ 560
