Explanation

Total cost = Rs2400 for 3000 copies. 500 copies given free, so 2500 copies for sale. Published price = Rs3.25 with 25% discount, selling price = Rs3.25×0.75 = Rs2.4375. Free copies: for every 25 bought, 1 free, so for 2500 sold, 100 free copies. Total copies actually sold = 2400. Revenue = 2400×2.4375 = Rs5850. Gain = 5850-2400 = Rs3450. Gain% = (3450/2400)×100 = 143.75% ≈ 144%.
