by selling a jacket for rs 729 sunanda lost 10 % what was the cost price ??

Answer:

Loss% = (CP - SP)/CP x 100 (Where CP = Cost Price and SP = Selling Price).

Selling Price of Jacket = Rs. 729.

Loss% = 10%.

So:Loss% = (CP - SP)/CP x 100

10 = (CP - 729)/CP x 100

10CP = 100CP - 72900

10CP - 100CP = - 72900

- 90CP = - 72900

CP = 72900/90 = Rs. 810.

Let CP = 100

Profit% = 10%

Profit = 10/100 * 100 = 10

SP = CP - Loss

SP = 100 - 10 = 90

If SP is 90 , then CP = 100

If SP is 1 , then CP = 100/90

If SP is 729 , then CP = 100/90 * 729 = 810

Hence, CP = Rs 810
