P sold an item to Q at a 20% gain, and Q sold it to R at a loss of 10%. If R bought the item for ₹1,080, then at what price did P purchase it?
Explanation:
Q sold it for 10% loss for Rs, 1,080 ∴ His cost price = 1080/0.9 = Rs. 1,200
⇒ P sold it for 20% loss for Rs, 1,200 ∴ His cost price = 1200/1.2 = Rs. 1,000
Hence, option (a).
