 Q. $A$, $B$ and $C$ enter into a partnership by investing Rs 28000, Rs 32000 and Rs 18000. $A$ is working partner and gets a fourth of the profit for this services and the remaining profit is divided amongst the three in the ratio of their investments. What is the amount of profit that $B$ gets if $A$ gets a total of Rs 4995?
 ✖ A. Rs 1665 ✔ B. Rs 2960 ✖ C. Rs 2590 ✖ D. None of these

Solution:
Option(B) is correct

Investment ratio among $A,B$ and $C$

$=28000:32000:18000$

$=14:16:9$

Suppose total profit $= \text{Rs. }x$.

$A$'s profit for his service = $\text{Rs. }x\times \dfrac{1}{4}=\dfrac{\text{Rs. }x}{4}$

Remaining profit = $x-\dfrac{x}{4}=\dfrac{3x}{4}$

$A$'s profit according to his investment:

$=\dfrac{3x}{4}\times \dfrac{14}{14+16+9}=\dfrac{7x}{26}$

Then,

$\dfrac{x}{4}+\dfrac{7x}{26}=\text{Rs. }4995$

$\Rightarrow \dfrac{13x+14x}{52}=\text{Rs }4995$

$\Rightarrow x=\text{Rs }9620$

Hence, $B$'s profit = $\dfrac{3x}{4}+\dfrac{16}{39}$

$\Rightarrow \left(\dfrac{3\times 9620}{4}\right)\times \dfrac{16}{39}=\text{Rs. }2960$
