70% of employees are engineers. Out of which 50% of total employees are salaried engineers.

Hourly engineers = total engineers - salaried engineers = 70% - 50% = 20%

And: Option A

Let’s say there are 100 employees.

70 are engineers, and 50 are salaried engineers.

Thus, 20, or 20/100 = 20% of the employees are hourly engineers.
