Directions (6 – 10):
Number of females employees in IT department= 840
Percentage of female employees in IT department
= 100- (27+22+16) = 100-65= 35%
So,
35%= 840
100%= 840/35*100= 2400
So,
Male employees in the company= 5200- 2400= 2800
Operations department:
Female = 27/100*2400= 648
Male = 14/100* 2800= 392
Admin Department:
Female= 22/100* 2400= 528
Male= 30/100* 2800= 840
Production Department
Female= 16/100* 2400= 384
Male= 25/100* 2800= 700
IT Department:
Female = 840
Male= 11/100* 2800= 308
Marketing
Female = 0
Male = 2800- (392+ 840+ 700+ 308) = 560
6) Answer: c)
Total increase in employees= 20% of 700 + 25% of 308 + 60= 277
Percentage Increase= 277/2800* 100= 9.89%
7) Answer: e)
Total number of male employees in Admin and Production= 840+700= 1540
Total number of employees in these two departments
= > 840+528+700+384= 2452
Required percentage= (1540/2452)* 100= 62.8 %
8) Answer: d)
Average = (648+528+384+392+840+700)/3 = 3492/3=1164
9) Answer: a)
Let the number of male employees who left the job be x
Then,
700-x/384-x= 149/70
149x- 70x= 149 * 384 – 700*70
79x= 57216- 49000
X= 8216/79= 104
So,
Total number of employees who left= 104*2= 208
10) Answer: d)
Number of male employees in IT after the transfer of 92 males = 308+92= 400
Number of females in IT= 840 -70= 770
Required ratio = 400:770= 40:77
