Question
Ravi and Raj entered into a business where Ravi invested
Rs. 9,000. Raj withdrew his capital after 6 months. If their profit ratio at the end of the year was 3:2, what was Raj’s investment?Solution
ATQ,
Let Raj's investment = Rs. y
(9000 × 12) : (y × 6) = 3 : 2
→ 108000 / (6y) = 3 / 2
→ 18000 / y = 3 / 2
→ y = 18000 × (2 / 3)
→ y = Rs.12,000
