If investment of \(\frac{1}{6}\)A = \(\frac{1}{4}\)B = \(\frac{3}{10}\)C., If they invested for two years, find the profit of A after 2 years out of the total profit of 3000. 

1350

\(\frac{1}{6}\)A  = \(\frac{1}{4}\)B = \(\frac{3}{10}\)C  

Om solving → A  :   B  :   C

                     9  :   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

                   9     :       6     :     5 = 20

20 → 3000

A's profit → 9 → \(\frac{3000}{20}\) × 9 = 1350
