A, B and C enter into a partnership with capitals in the ratio $\frac{2}{3} : \frac{3}{5} : \frac{5}{6}$. After 8 months, A increases his share of capital by 25%.If at the end of the year, the total profit earned is ₹5,820, then the share of C in the profit is:

₹2,250

Capital Ratio of A , B & C

$\frac{2}{3} : \frac{3}{5} : \frac{5}{6}$

=  20  :  18   :  25

Increased investment of A = 20 + 25% of 20 = 25

Profit ratio of              A           :     B          :     C

                      25× 4 +20× 8    :   18× 12     :   25× 12

                              65             :      54         :       75

According to question ,

( 65 + 54 + 75)R = 5820

1R = 30

Profit of C = 30× 75 =  2250
