A dishonest dealer marks up his goods by 50% and then gives a discount of 20% on the marked price. Apart from this, he uses a faulty balance which reads 1kg for 900 gm. What is his net profit percentage (rounded off to the nearest integer)?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is Option 4 i.e. 33
We use the ratio method in this type of question
2 : 3 (marks up his goods by 50%)
5: 4 (gives a discount of 20% on the marked price)
900: 1000 ( uses a faulty balance which reads 1kg for 900 gm)
The net ratio is 3: 4
Hence, the net profit % = 1/3 × 100 = 33%
