Question

The selling price of an article is rs. 4550 and its loos percent is 9% find the price of the article

Answer 1

Answer:Let the CP be Rs 100.

Loss = 9% i.e. Rs 9

SP will be Rs (100-9) =Rs 91

Now, By Unitary method

If 91 is SP , then 100 is CP.

And if 4550 is SP , CP will be 100/91 *4550 = Rs 5000.

Now, New SP = 4825

We can see , CP is greater than SP , so again loss = (5000-4825) = Rs 175.

Loss % = 175/5000 *100 = 7/2 = 3.5

Answer 2

Step-by-step explanation:

CP = 100/100-Loss% * SP

CP = 100 / 100-9 = 100/91 * 4550

CP = 100 / 91 * 4550

CP = 100 * 4550 / 91

CP= 455000 / 91

CP = 5000.
