To solve this problem, let's break it down step by step.

Step 1: Calculate the total salary of the 13 employees

The average salary of the 13 employees is 31,567 kr. So, the total salary of all 13 employees can be calculated by multiplying the average salary by the number of employees:

$\text{Total salary of 13 employees} = 31,567 \, \text{kr} \times 13 = 410,371 \, \text{kr}$

Step 2: Calculate the total salary of the 14 employees after the new hire

After the new employee joins, the average salary increases by 240 kr, making the new average salary:

$\text{New average salary} = 31,567 \, \text{kr} + 240 \, \text{kr} = 31,807 \, \text{kr}$

Now, to find the total salary of all 14 employees, multiply the new average salary by 14:

$\text{Total salary of 14 employees} = 31,807 \, \text{kr} \times 14 = 445,298 \, \text{kr}$

Step 3: Calculate the salary of the new employee

The salary of the new employee is the difference between the total salary of 14 employees and the total salary of the original 13 employees:

$\text{New employee's salary} = 445,298 \, \text{kr} - 410,371 \, \text{kr} = 34,927 \, \text{kr}$

Final Answer:

The new employee's salary is 34,927 kr.
