Given:
A dishonest trader says to customers that he sells his goods at a cost price, but he uses a false weight and gains 12.5% as profit.
Formula Used:
Gain % = [(Error)/(True value – Error)] × 100
Solution:
12.5 % = [Error/(1000 – Error)] × 100
=> 1/8 = [Error/(1000 – Error)]
=> 8Error + Error = 1000
=> 9Error = 1000
=> Error = 1000/9
So, the trader gives 1000 - 1000/9
=> [9(1000) - 1000]/9
=> (9000 - 1000)/9
=> 888.8 g
