Question
Two individuals, Karan and Arjun, invested in a
business. Karan invested Rs. (x + 250) for 9 months, while Arjun invested Rs. (x – 450) for 6 months. If Arjun’s profit share was Rs. 3600 out of a total profit of Rs. 9000, determine the value of x.Solution
ATQ,
Karan’s share = 9000 – 3600 = Rs. 5400
So, {(x + 250) × 9}:{(x – 450) × 6} = 5400:3600
Or, 27(x + 250) = 18(x – 450)
Or, 27x + 6750 = 18x – 8100
Or, 9x = 14850
Or, x = 1650
