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 number of post graduate male employees working in company C
= 18.75% of 24/100× 400 =3/16 × 96 = 18
The number of post graduate female employees working in company C
= 12.5% of (24/100 × 700 – 24/100 × 400) = 1/8 × 72 = 9
Hence, the total number of post graduate employees working in the company C = 18 + 9 = 27
