David sells his Laptop to Goliath at a loss of 20% who subsequently sells it to Hercules at a Profit of 25%. Hercules, after finding some defect in the laptop, returns it to Goliath but could recover only Rs. 4.50 for every Rs. 5 he had paid. Find the amount at Hercules' loss if David had paid Rs. 1.75 lakh for the laptop.

Answer: Option C

David (100) == 20% ↓(loss) ⇒ Goliath (80) == 25% ↑(gain) ⇒ Hercules(100) == 10% ↓ (loss) ⇒ Goliath (90)
Hercules loss corresponds to 10 when David buys the laptop for Rs. 100.
Thus, Hercules loss would be Rs. 17,500 when David buys the laptop for 1,75,000.
