A dishonest merchant sells goods at a 12.5% loss on the cost price, but uses 28 g weight instead of 36 g. What is his percentage profit or loss?

Show answer & explanation

Correct answer: B

Explanation

The correct answer is Option 2. i.e. 12.5% gain.

Percentage gain by using 28 g weight instead of 36 g = 36−2828×100=2007%\frac{36-28}{28} \times 100=\frac{200}{7} \%

Percentage loss = 12.5%

Considering 12.5% loss as -12.5% profit,

Now, the final percentage profit/loss = 2007−12.5−2007×12.5100=+12.5%\frac{200}{7}-12.5-\frac{\frac{200}{7} \times 12.5}{100}=+12.5 \%

∴ His percentage profit is 12.5%
