A, B, and C started a business by investing 30%, by a, 14.28% of the remaining by B, and the remaining by C. If the period of their investment was 2 years, 1 year, and 6 months, find the ratio of their profit at the end.
Answer & explanation
Correct answer: option 1
A = 30% (Let total 100)
B ⇒ \(\frac{100-30 × 14.28}{100}\)
= 70 × \(\frac{1}{7}\) = 10%
C = 100 - 30 -10 = 60%
A : B : C
Inv. → 30 10 60
Time → 2 1 0.5
--------------------------
Profit → 60 10 30
6: 1 : 3
