A starts a business with Rs. 40,000. After 4 months, B joins the business with Rs. 80,000. After 6 months, C joins the business with Rs. 1,20,000. Find the ratio of their capital.
A
6 : 8 : 9
B
9 : 8 : 6
C
8 : 6 : 9
D
None of these
Correct Option:
A
Explanation
Profit is shared according to capital × time: A invested Rs. 40,000 for 12 months = 40,000 × 12 = 480,000. B invested Rs. 80,000 for 8 months = 80,000 × 8 = 640,000. C invested Rs. 1,20,000 for 6 months = 1,20,000 × 6 = 720,000. Ratio = 480,000 : 640,000 : 720,000 = 6 : 8 : 9.
