\(\frac{1}{4}\) of A's capital = \(\frac{1}{3}\) of B's capital = \(\frac{2}{5}\) of C's capital. If they invest for four years, then find the profit of A after 4 years out of the total profit of 9500 .
Answer & explanation
Correct answer: option 3
\(\frac{1}{4}\)A = \(\frac{1}{3}\)B = \(\frac{2}{5}\)C
3A = 4B , 5B = 6C
A : B B : C
4 : 3 6 : 5
On solving → A : B : C
8 : 6 : 5
Note → If the period of all the investors is the same then there is no effect of time on profit
A : B : C
8 : 6 : 5 = 19R
19R = 9500
A's profit → 8 → \(\frac{9500}{19}\) × 8 = 4000
