\(\frac{1}{5}\) of A's capital = \(\frac{1}{6}\) of B's capital = \(\frac{2}{3}\) of C's capital. If they invest for three years, then find the profit of A after three years out of the total profit of 7500 .
Answer & explanation
Correct answer: option 4
\(\frac{1}{5}\)A = \(\frac{1}{6}\)B = \(\frac{2}{3}\)C
6A = 5B , 3B = 12C
A : B B : C
5 : 6 12 : 3
On solving → A : B : C
10 : 12 : 3
Note → If the period of all the investors is the same then there is no effect of time on profit
A : B : C
10 : 12 : 3 = 25R
25R = 7500
A's profit → 10 → \(\frac{7500}{25}\) × 10 = 3000
