Correct Answer - Option 3 : 28%
Calculation:
Let the CP to Amir = 100
Due to a loss of 10% in CP, the SP will be = 90
According to the question:
Amir bought the article at 20% discount on Marked Price. Therefore, the equation is
⇒ 80/100 of Marked Price = 100
⇒ Marked Price = 125
Now, loss in value if the item was bought at MP = MP – SP
⇒ 125 – 90
⇒ 35
∴ Loss% = 35/125 × 100
⇒ 28%
The percentage loss is 28%.
