Explanation:

Given that the difference of the total number of employees (male and female) working in companies A and B = 21
So, total number of employees (male and female) working in all the given 5 companies =21/(18-15) X 100=700

Number of employees (male and female) working in the company A = 15/100 × 700 = 105
So, number of male employees working in the company A =38(2/21)% of 105 = 800/2100 × 105 = 40
Total number of male employees working in all the given 5 companies = 40/10 × 100 = 400
The central angle of total number of male employees working in company A = 10/100 × 360° = 36°
