Brrunno [24]

Answer:

There are a total of <u>71,551 employees</u> in the company.

Explanation:

Let the number of employees in the company be 'x'.

Given:

Number of employees in one country = 24900

As per question:

34.8% of total employees = 24900

⇒ 34.8\%\times x=24900

\frac{34.8}{100}\times x=24900\\\\0.348x=24900\\\\x=\frac{24900}{0.348}\\\\x=71,551.7\approx71,551

So, there are a total of 71,551 employees in the company.
