- A. 5 : 7 : 8
- B. 5 : 7 : 8
- C. 5 : 7 : 8
- D. 5 : 7 : 8
Answer: Option B
Explanation:
Hints: let the investment Take was x for 14 months, y for 8 months and z for 7 months
14x : 8y : 7z = 5: 7 : 8
so, 14x/8y = 5/7
y = 49x/20
and 14x/7z = 5/8
z = 16x / 5
x : y : z = x : 49x/20 : 16x /5 = 20 : 49 : 64
