A dealer makes a profit equal to the selling price of 4 pens when he sells a total of 12 pens. What is his profit percentage?
Show answer & explanation
Correct answer: C
Explanation
Correct Answer: Option 3 (50%)
Short Solution:
Assume Selling Price (SP) of 1 pen = ₹1
- SP of 12 pens = ₹12
- Profit = SP of 4 pens = ₹4
So,
Cost Price (CP) = SP − Profit = 12 − 4 = ₹8
\text{Profit %} = \frac{4}{8} \times 100 = 50\%
