Option 4 : Quantity I > Quantity II
Quantity I:
Selling price = Rs. 2750
Profit percentage = 10%
Cost price of an item = 2750 × 100/110 = Rs. 2500
Marked price of an item = 2500 × 125/100 = Rs. 3125
Discount percentage = 2%
Selling price after 2% discount = 3125 × 98/100 = Rs. 3062.5
Profit percentage = (3062.5 – 2500)/2500 × 100
Profit percentage = 22.5%
Quantity II:
Simple Interest earned by Rohan in 2 years =
= (2500 × A × 2/100) + (3000 × 2 × B/100)
= 50A + 60B
Profit he had = 2320
⇒ 50A + 60B = 2320
⇒ 5A + 6B = 232
Simple Interest earned by interchanging rates of interest =
= (2500 × B × 2/100) + (3000 × 2 × A/100)
= 50B + 60A
Profit he had = 2300
⇒ 50B + 60A = 2300
⇒ 6A + 5B = 230
Solving,
A = 20% and B = 22%
So, we can observe Quantity I > Quantity II.
