U, V and W invest $\text{₹}18,000$, $\text{₹}24,000$ and $\text{₹}30,000$ respectively in a business. If the profit at the end of the year is $\text{₹}14,400$, how much less is V's share of the profit than that of W?

The profit earned in a partnership is distributed in direct proportion to the investments made by the partners:
$$\text{Ratio of profit shares (U : V : W)}=18000:24000:30000$$

$$\text{Simplified Ratio}=3:4:5$$

Total sum of ratio parts = $3+4+5=12$ parts.
Total profit = $\text{₹}14,400$.

Value of $1$ part:

$$\text{Value per part}=\frac{14400}{12}=\text{₹}1200$$

Difference between W's share ($5$ parts) and V's share ($4$ parts) is:

$$\text{Difference}=5-4=1\text{ part}$$

$$\text{Difference in profit}=1\times 1200=\text{₹}1,200$$
