Choose the correct answer from the alternatives given.
A starts a business with Rs. 3500 and after 5 months, B joins with A as his partner. After a year. the profit is divided in the ratio 2 : 3. What is B's contribution in the capital?

• A. Rs. 8000
• B. Rs. 8500
• C. Rs. 9000
• D. Rs. 7500

Answer 1

Answer: (C)

Rs. 9000

Let the investment of B be $I_B$.
According to the question,
Ratio of profit = Ratio of investment $\times$ Time
$P_A:P_B=I_A\times T_A:I_B\times T_B$
$2:3=3500\times 12:I_B\times 7\Rightarrow 2:3=42,000:I_B\times 7$
$\frac{2}{3}=\frac{42,000}{I_B\times 7}:=9,000$
Hence, investment of B is Rs. 9,000.
