A trader a weighing balance that shows 1300 g for a kg. He further marks up his cost price by 15%. The net profit percentage is :
Answer & explanation
Correct answer: option 2
Let the cost price per g be Rs. 1
So, cost price of 1300 g = Rs. 1300
Marked price of 1300 g = 1300 × 115%
⇒ Rs. 1495
Now, the trader gives 1000 g instead of 1300 g
So, his profit = 1495 - 1000 [As cost price of 1000 g is Rs. 1000]
⇒ 495
Profit% = \(\frac{495}{1000}\) × 100
⇒ 49.5%
