Person A started a business by investing Rs. 65,000. After a few months, B joined him by investing Rs. 50,000. Three months after the joining of B, C joined the two with an investment of Rs. 55,000. At the end of the year, A got 50% of profit as his share. For how many months did A alone finance the business?

Answer: Option B

Solution

Answer: Option B

Solution:

A got 50% of share and remaining 50% divided in B and C
∴ 10x + 30 + 11x = 156
⇒ 21x = 126
⇒ x = 6
B did for = 9 months
C did for = 6 months
∴ A alone did business for = 3 months
