মনেকরি,
5 বছর পূর্বে পিতার বয়স = 5x বছর
এবং পুত্রের বয়স = x বছর
.:. বর্তমানে পিতার বয়স = (5x + 5) বছর

প্রশ্নমতে, 5x + 5 + 2 = 3 (x + 5 + 2)
⇒ 5x + 7 = 3(x + 7)
⇒ 5x + 7 = 3x + 21
⇒ 2x = 14
⇒x = 7
.:. বর্তমানে পিতার বয়স 5 × 7 + 5 = 40 বছর
বর্তমানে পুত্রের বয়স = 7 + 5 = 12 বছর
.:. পিতা ও পুত্র = 40 : 12 = 10 : 3

Let the total profit be Tk. z. Then, B's share = Tk.. 2z/3, A's share = Tk. ( z - 2z/3 ) = Tk. z/3. A : B = z/3 : 2z/3 = 1:2 Let the total capital be Tk. X and suppose B's money was used for x months. Then. (1(x) / 4 * 15) / (3x) / 4 * y) = 1/2 < = > y = (15 * 2 / 3) = 10 . Thus, B's money was used for 10 months.
