E Correct answer
Explanation

Original ratio 7:8:6 on sum 8400 gives parts: (7+8+6) = 21 parts, each part = 8400/21 = 400. So original shares are: 7×400 = 2800, 8×400 = 3200, 6×400 = 2400. After adding 400 to each: 2800+400 = 3200, 3200+400 = 3600, 2400+400 = 2800. Simplified ratio: 3200:3600:2800 = 8:9:7 (dividing by 400). Option E is correct.
