In a business, Pintu invested \(1\frac{1}{2}\) times the amount Aman did, and David invested \(2\frac{1}{2}\) times Aman's amount. So, the ratio of the capital contributions of Aman, Pintu, and David is \(2:3:5\).
Letâs assume Aman invested \(x\) units of money. Therefore: - Pintu invested \(x \times 1\frac{1}{2} = \frac{3x}{2}\) - David invested \(x \times 2\frac{1}{2} = \frac{5x}{2}\) So the ratio of their capitals is: \[ x : \frac{3x}{2} : \frac{5x}{2} = 1 : \frac{3}{2} : \frac{5}{2} \] Multiplying all terms by 2 to eliminate fractions: \[ = 2 : 3 : 5 \]
