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,
$$\frac{{{\text{Goods Left}}}}{{{\text{Goods Sold}}}} = \frac{{300 \times 100}}{{900}} = $$ $$33.33\% $$
This Question Belongs to Arithmetic Ability >> Profit And Loss
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%
