A Correct answer
Explanation

Let CP = x. At 25% loss on SP, selling price = 0.75x. When SP increases by 108, new SP = 0.75x + 108, which gives 20% profit, so 0.75x + 108 = 1.20x. Solving: 108 = 0.45x, so x = 240. The key is understanding profit/loss is calculated on SP in the first scenario, then the SP increase creates a new situation with 20% profit.
