\(\frac{1}{2}\) of A's capital = \(\frac{1}{3}\) of B's capital = \(\frac{3}{5}\) of C's capital. If they invest for two years, then find the profit of A after two years out of the total profit of 4500.
Answer & explanation
Correct answer: option 4
\(\frac{1}{2}\)A = \(\frac{1}{3}\)B = \(\frac{3}{5}\)C
3A = 2B , 5B = 9C
A : B B : C
2 : 3 9 : 5
On solving → A : B : C
6 : 9 : 5
Note → If the period of all the investors is the same then there is no effect of time on profit
A : B : C
6 : 9 : 5 = 20R
20R = 4500
A's profit → 6 → \(\frac{4500}{20}\) × 6 = 1350
