Given:
A, B and C started a business with their investments in the ratio 1 : 2 : 4.
To find:
The ratio of their profits at the end of the year.
Solution:
1) Let the investment will be 2:4:8 (this makes the calculation easy).
2) We will do it in the ratio form only because the total investment over the year is the ratio of the profit only.
3) Investment in the parts of the 6 months.
- (2×6)+(3×6) : 4×12 : (8×6)+(6×6)
- 30 : 48 : 84
- 5 : 8 : 14
The ratio of their profits at the end of the year is 5:8:14.
