To find the total profit of the company, follow these steps:

1. Determine the ratio of profit shares:

The profit is divided in the ratio \(4:5\). Let's denote the profits of X and Y as \(4k\) and \(5k\) respectively.

2. Set up the equation based on the information given:

We know that Y received N5000 more than X. Therefore:

\[
5k - 4k = 5000
\]

\[
k = 5000
\]

3. Calculate the total profit:

Total profit = Profit of X + Profit of Y

\[
\text{Total profit} = 4k + 5k = 9k
\]

Substituting \(k = 5000\):

\[
\text{Total profit} = 9 \times 5000 = 45000
\]

The total profit of the company for the year is:

D. 45000
