Question
Meena and Rina started a business with Rs. 3500 and Rs.
2500 respectively. After 2 months, Tina joined with an investment of Rs. ‘x’. If Meena got Rs. 560 out of a total Rs. 1400 profit after one year, determine the value of ‘x’.Solution
ATQ, Given: Meena: ₹3500 for 12 months → 3500×12=42000 Rina: ₹2500 for 12 months → 2500×12=30000 Tina: ₹x for 10 months → x×10=10x Profit ratio = Meena : Rina : Tina = 42000 : 30000 : 10x Simplifies to = 42 : 30 : x Meena’s share of total profit: Total profit = ₹1400 Meena's share = ₹560 So,
