Explanation:

x*8 : 3*5 : y*6
8x : 15 : 6y
So 8x/(8x+15+6y) * 39650 = 10400
Solve, 225x – 60y = 150
15x – 4y = 10……………………………………(1)
Also
6y/(8x+15+6y) * 39650 = 19500
Solve, 61y = 75 + 40x + 30y
40x – 31y = -75………………………………….(2)
Solve equations (1) and (2)
x = 2, y = 5
So ratio of investment is x : 3 : y = 2 : 3 : 5
