A. 30%

B. 20%

C. 25%

D. 33.33%

E. None of these

Answer: Option D

Solution(By Examveda Team)

While purchasing he would take 1200 grams for the price of 1000 grams. While selling he would sell 900 grams for the price of 1000 grams.
Since, CP = SP
The profit earned by him,
$$\frac{{{\text{Goods Left}}}}{{{\text{Goods Sold}}}} = \frac{{300 \times 100}}{{900}} = $$       $$33.33\% $$

    what if he was selling 1200 gms he purchased from the seller and weighs it at 10% less ie.. 1080gms so total profit would be 320 (2400-1080) and 320/1080*100 is not 33.33%
