Question
‘Rina’ and ‘Meena’ invested Rs. 1,800 and Rs. 3,000
respectively in a startup. After 15 months, Rina increased her capital by 50% while Meena decreased hers by Rs. 600. If the total profit after 3 years is Rs. 5,400, what is the profit difference between them?Solution
ATQ,
Increased investment of ‘Rina’ = 1800 × 1.50 = Rs. 2,700
Decreased investment of ‘Meena’ = 3000 – 600 = Rs. 2,400
So, ratio of profit shares of ‘Rina’ and ‘Meena’ = (1800 × 15 + 2700 × 21):(3000 × 15 + 2400 × 21) = 13.5:16.2 = 15:18
Difference between profit shares = 5400 × {(18 – 15) ÷ (18 + 15)} = Rs. 600
