T and U start a business. T invests ₹40,000. After 3 months, U joins with ₹60,000. After 3 more months, T doubles his capital. If the business runs for 12 months, find the profit ratio of T to U.
Show answer & explanation
Correct answer: A
Explanation
First 6 months = 40,000 × 6 = 240,000
Next 6 months = 80,000 × 6 = 480,000
Total = 720,000
U's investment = 60,000 × 9 = 540,000
Profit ratio = T : U
= 720,000 : 540,000
= 4 : 3
