?A? sold an article for Rs. 8000 and incurred a loss. Had he sold the article for Rs. 9800 his gain would have been twice the amount of los…

Solution
let the cost price of article be Rs C
As selling price is Rs 8000 ,loss = Rs (C - 8000 )
Now if selling price is changed to Rs 9800 then profit = Rs (9800 -C)
Given that 9800 - C = 2(C-8000)
C = 25800 /3 = Rs 8600
In order to earn 20 percent profit the selling price should be 1.2 C = 1.2 × 8600 = Rs 10320
