Question

by selling an article for rs 240 a man makes a profit of 20% .find the cp what would be his %profit if he sold the article of rs 275.

plz solve fast i will mark as brainlist.

Answer 1

Cp is
$\frac{100}{120} \times 240= 200$
Profit in 2nd case is 75rs therefore
Profit per cent is
$\frac{75}{200} \times 100 \%= 37.5\%$

Answer 2

Let the cost price of the article be x.

Given that selling price of the article = 240.

Given that Profit = 20%.

SP = x + 20x/100

240 = x + 20x/100

240 = x + x/5

240 = 6x/5

1200 = 6x

x = 1200/6

x = 200.

Therefore the cost price of the article = 200 rupees.

Given selling price = 275.

We know that profit = SP - CP

                                  = 275 - 200

                                  = 75.


Profit % = (Profit * 100/CP)

              = (75 * 100/200)

              = 37.5%.


Hope this helps!
