A, B, C enter into Partnership. A invests 3 times as much as B invests and B invests two-thirds of what C invests. At the end of the year, the profit earned is $6600. What is the share of B?

A = 3B

B = \frac{2}{3} C

A + B + C = 6600

Substitute and solve, though investment does not necessarily mean profitâ€¦
