Question

a seller gets 28% loss on selling a table in 810 rupees.if he sells it in 900 rupees then find his gain /loss percentag.​

Answer 1

Heya!!

Here's your answer:

Given,

SP (Selling Price) = 810

Loss% = 28%

Now,

Loss% = (CP - SP)/CP * 100 = 28

Putting value of SP,

(CP - 810)/CP * 100 = 28

CP - 810/CP = 28/100

CP - 810 = 7/25CP

CP - 7/25 CP = 810

18CP/25 = 810

18CP = 810 * 25

CP = 45 * 25 = 1125

Now, we know

CP = 1125      

In this case,

SP = 900

Loss = 1125 - 900 = 225

Loss% = 225/1125 * 100

= 100/5

= 20%

Therefore, the loss % = 20 %
