Answers: 1.c 2.b 3.c 4.e 5.b
Solution
1.       Number of female employees in B and C= 2100*(75/25)=6300
Total number of employees in B and C=22000*(65/100)=14,300

Percentage=(6300/14300)*100= 44% (Approx.) (c)

2.       Number of married female employees in company A= (40/100)*2100= 840
Total number of people working in company A= 7700
Total number of married people working in company A=2500
So, Number of married male employees= 2500-840= 1660
Total males in company A= 7700-2100= 5600
Number of unmarried male employees= 5600-1660= 3940
Percentage= 70% (Approx.) (b)

3.       1/3th of the female employees are living with their husbands= 2800
34% of the females are unmarried or 66% are married.
Married females= 8400*(66/100)= 5544
Female employees who are married but not living with their husbands= 5544-2800
= 2744 (c)

4.       Employees in the age group 30 years and above is as follows
A-     7700-20% of 7700= 6160
B-      5500-25% of 5500= 4125
C-      8800-30% of 8800= 6160
Answer is both A and C (e)

5.     Present staff strength of C= 8800
After 20% increase in 2015: 1.20*8800= 10560
After 10% decrease in 2016: 0.90*10560= 9504
Increase in staff strength of C= 9504-8800= 704 (b)
