Countries Officers Total no. employees Respective of male and Females employees Percentage of postgraduate employees
A 16 2568 5:7 75
B 18 2880 11:5 65
C 14 2310 10:11 40
D 22 3575 3:2 60
E 13 2054 7:6 50
F 17 2788 20:21 75

(c) 72

n country H, 80% are post-graduate. That is = [80/100]*3360 = 2688
Male is given 1800. Hence, female post-graduate employees = 2688 – 1800 = 888
Total female employees is = [5/14]*3360 = 1200
Hence, required percentage = [888/1200]*100 = 74 Percent.

6. In which of the given countries is the percentage of women employees to the number of employees (both male and female) in that country the second lowest?

(a) G

(b) B

(c) E

(d) H

(e) D

(d) H Country B = 11:5 à [5/16]*100
Now, let’s say this is approximately 30% (16*3 = 48 which is close to 50).
Country D = [2/5]*100 = 40%
Country E = [6/13]*100 = approx. 45%
Country G = [7/15]*100 = approx. 45%
Country H = [5/14]*100 = approx. 35%
Now, second highest is Country H. Question solved.

7. What is the respective ratio between total number of male employees in countries B and H together and total number of female employees in countries C and D together?

(a) 63:52

(b) 51:38

(c) 77:64

(d) 69:44

(e) 57:40

(d) 69:44

Total male employees from countries B and H = [11/16]*2880 + [9/14]*3360 = 1980 + 2160 = 4140
Total female employees from Countries C and D = [11/21]*2310 + [2/5]*3575 = 1210 + 1430 = 2640
Required ratio = 4140:2640 = 69:44.

(e) 294

(e) 75% of 2568 is required. Divide 2788 in four parts and add three parts. Thus 2568/4 is 642 and 642*3 = 1926
65% of 2880 is required. Divide 2880 in ten parts and add six parts and half of 7th part. Thus 288*6 + 288/2 = 1728 + 144 = 1872
60% of 3575 is required. Divide 3575 in 5 parts and add three parts. Thus 3575/5 = 715 and 715*3 = 2145
Average of these three is = [1/3]*[1926+1872+2145] = 1981
Using similar procedures, average of other three is calculated as = 2275
Difference = 2275 – 1981 = 294.

B = 2880/18 = 1440/9 = 160
C = 2310/14 = 330/2 = 165
D = 3575/22 = 325/2 = 162.5
F = 2788/17 = 164
H = 3360/21 = 480/3 = 160
Highest is in country C.
