A shopkeeper marks his goods 20% above the cost price. A man purchased that goods at a discount of 25% on marked price but also paid 15% GST on discounted price. If the man sold it for Rs 6000 therefore the man earned a profit of 25% on original cost price. Find at what price the man purchased that goods from the shopkeeper.

This is a complete and solvable profit/loss question. Working backwards: The man sold for Rs 6000 at 25% profit on original cost, so original cost = 6000/1.25 = Rs 4800. Shopkeeper marked 20% above cost: 4800 × 1.20 = Rs 5760. Man got 25% discount on marked price: 5760 × 0.75 = Rs 4320. Then paid 15% GST: 4320 × 1.15 = Rs 4968. Option C (4968) is correct. The question properly tests understanding of marked price, discount, GST, and profit calculations.
