Question

A and B invested Rs.7,000 and Rs.10,000 respectively in a business. A left the business with his money after 9 months and at the end of the first year they earned a profit of Rs. 6100. What is the share of B in the profit?
1. Rs. 4800
2. Rs. 5600
3. Rs. 2600
4. Rs. 4000

Answer 1

Correct Answer - Option 4 : Rs. 4000

Given

A started the business = Rs 7000 

B started the business = Rs 10,000 

Formula 

Investment = capital × time 

Profit ratio is equal to investment ratio

Calculation 

A Investment for 9 months = 7000 × 9 = 63,000

B Investment for 12 months = 10,000 × 12 = 1,20,000

⇒ Investment Ratio (A : B) = 63,000 : 1,20,000 = 21 : 40 

⇒ Profit Ratio = 21 : 40 

⇒ Total Profit = 6100

⇒ 61x = 6100 

⇒ x = 100 

⇒ Profit Share of B = 40 × 100 = Rs 4000 

∴The profit share of B is Rs 4000
