Common calculation

Total number of employees in company A is 9000 × 12 /100 = 1080

Total number of male employees in company A is 4000 × 22/100=880

Total number of female employees in company A is 1080 – 880 = 200

Calculation

Males = 880

40% of males are married → Married males = 40% of 880 = 0.4 × 880 = 352

Total married employees in A = 436

So, Married females = 436 - 352 = 84

Total females = 200

So, Unmarried females = 200 - 84 = 116

We are told unmarried females = 4x
⇒ 4x = 116
⇒ x = 29

x = 29
