Three men, A,B and C upon forming a partnership, invest $1,800, $2,500 and $4,000 respectively. The net profits at year's end amounted to $415. How many dollars should B's share the profit be?

Whatever fraction $2500 is of the total invested ($8,300) .

Multiply (25/83) by $415.

125

To determine B's share of the profit, we need to calculate the ratio of B's initial investment to the total initial investment in the partnership.

The total initial investment is the sum of the individual investments of A, B, and C: $1,800 + $2,500 + $4,000 = $8,300.

To find the ratio, we divide B's investment by the total investment: $2,500 / $8,300 ≈ 0.3012.

Now, we can calculate B's share of the profit by multiplying the net profit by the ratio: $415 x 0.3012 ≈ $125.19.

Therefore, B's share of the profit should be approximately $125.19.
