We know that ratio of profit share is equal to ratio of capital invested.

Ratio of capitals of three persons is = 3:8:5 .

∴ Ratio of profits of three persons is = 3:8:5

Given, profit of 1^st person is ₹60 less of the 3^rd person.

Let their profits be 3x, 8x and 5x.

5x-3x = 60

2x = 60

X = 30

Thus, Total profit = 3×30 + 8×30 + 5×30

= 90 + 240 + 150

= ₹480
