A, B and Centered into partnership, and provided capital of $\text{ ₹ }$22,000, $\text{ ₹ }$26,000 and, $\text{ ₹ }$34,000 respectively. Some months later $\text{ ₹ }$10,000 extra capital being needed. it was supplied by B.At the end of 12 months the total profit wast $\text{ ₹ }$50,274, and A's share was? $\text{ ₹ }$12,474. When did B supply the extra capital?

A's total capita! in partnership is 22000 x I 2 = 264000. B'sto1alis26000x 12=312000 

C's total is 34000 x 12 =408000 

Let B invested  $\text{ ₹ }$10000 for x months then this amount 

will be 10O00x.

Total amount is 264000 + 312000 + 408000 + l O000x = 984000 + 10000x 

Then $\frac{264000}{984000+10000x}=\frac{12474}{50274}\Rightarrow x=8$

So B supply the extra capital after 4 months.
