Answers :

1) Answer: A

Number of HR employees in all the companies together = 40/100 * (3200 + 2600 + 1400 + 2400 + 1300 + 1200) = (12100/100) * 40= 4840

2) Answer: B

= 2:1

Number of female employees = 1200 * 1/3 = 400

3) Answer: A

Required difference = (3200 + 1400)/2 – (1300 + 2400)/2

= (4600/2) – (3700/2)

= 2300 - 1850

= 450

4) Answer: B

Required percentage = 3200/(3200 + 2600 + 1400 + 2400 + 1300 + 1200) * 100

= (3200/12100) * 100

= 26.44%

5) Answer: D

Required ratio = (3200 + 2600 + 1400):(2400 + 1300 + 1200)

= 7200 : 4900

= 72:49
