A, B and C subscribe to a business of $\text{Rs. }50,000$. B subscribes $\text{Rs. }6,000$ more than C and A subscribes $\text{Rs. }2,000$ more than B. What will be A's share of profit out of a total profit of $\text{Rs. }10,000$?

Let the subscription of C be $x$.
Then, subscription of B $=x+6,000$.
Subscription of A $=(x+6,000)+2,000=x+8,000$.

The total subscription is given as $\text{Rs. }50,000$:

$$x+(x+6,000)+(x+8,000)=50,000$$

$$3x+14,000=50,000$$

$$3x=36,000⟹x=12,000$$

Now, determine the individual subscriptions:

* C $=12,000$
* B $=12,000+6,000=18,000$
* A $=12,000+8,000=20,000$

The ratio of profit sharing is equal to the investment ratio $A:B:C$:

$$20,000:18,000:12,000=10:9:6$$

Total ratio parts $=10+9+6=25$.

A's share of profit out of $\text{Rs. }10,000$:

$$\text{A’s profit}=\left(\frac{10}{25}\right)\times 10,000=10\times 400=\text{Rs. }4,000$$
