Question

If a person sells an article for Rs. 530 at

some loss and the loss becomes double when

he sells it for Rs. 510. Find the C.P. of the

article.

Answer 1

To find C.P you have to do this process
CP = SP + Loss
CP =Rs. 530 +Rs. 510 =1040
So,the CP of article is 1040

Answer 2

Answer:

CP = LOSS +SP

let loss on 530 is X

then according to question

1. CP= X + 530 ....eq1

loss on 510 will be 2X according to question

CP = 2X + 510 ....eq2

comparing both equations

X + 530 = 2X + 510

X =20

PUTTING VALUE OF X

CP=550
