From the profits of a certain investment, Faisaf got \(1/3\) of the total profit and three of his friends each got \(1/3\) of the rest. What was the total profit? 1) Faisal and one of his friends got \(5/9\) of the total profit. 2) Two of Faisal's friends got a total of 48000 taka.

Explanation: Let \(x\) be the total profit. Faisal's share: \(1/3 x\). Remaining profit: \(x - 1/3 x = 2/3 x\). Each of the 3 friends' share: \(1/3\) of the rest: \(1/3 \times (2/3 x) = 2/9 x\). Statement 1: Faisal and one friend's share is \(5/9\) of total. \((1/3 x) + (2/9 x) = (3/9 x) + (2/9 x) = 5/9 x\). This confirms the shares but doesn't give the value of \(x\). Not sufficient. Statement 2: Two friends' total share is \(48000\). Two friends' share = \(2 \times (2/9 x) = 4/9 x\). So, \(4/9 x = 48000\). This allows solving for \(x\): \(x = 48000 \times 9 / 4 = 12000 \times 9 = 108000\). Sufficient. Statement (2) ALONE is sufficient.
