Answers :
Directions (1-5) :
1) Answer: B
Number of female HR employees in A in March = 60/100 * 7600 = 4560
Number of male HR employees in A in March = 40/100 * 7600 = 3040
Number of female HR employees in C in March = 125/100 * 4560 = 5700
Number of male HR employees in C in March = 9820 – 5700 = 4120
Required percentage = 4120/3040 * 100 = 135.52%
2) Answer: A
Number of female IT employees in A in June = 7500 * 48/100 = 3600
Number of female IT employees in C in June = 3600 * 110/100 = 3960
Total number of IT employees in C in July = 7950
Number of female IT in C in July = 40/100 * 7950 = 3180
Required percentage = (3960 – 3180)/3960 * 100 = 19.69%
3) Answer: D
Number of female sales employees in A in march = 65/100 * 6200 = 4030
Number of female sales employees in A in April = 40/100 * 5550 = 2220
Number of female sales employees in A in May = 45/100 * 4800 = 2160
Number of female sales employees in A in June = 56/100 * 6500 = 3640
Number of female sales employees in A in July = 70/100 * 7600 = 5320
Required total = 4030 + 2220 + 2160 + 3640 + 5320 = 17370
4) Answer: C
Total number of HR employees in B in March = 4850
Regular HR employees in B in March = 60/100 * 4850 = 2910
Total number of sales employees in A in April = 5550
Regular sales employees in A in April = 40/100 * 5550 = 2220
Required difference = 2910 – 2220 = 690
5) Answer: A
Total number of sales employees in B in July = 8700
Number of female sales employees in B in July = 40/100 * 8700 = 3480
Total number of sales employees in C in April = 7840
Number of female sales employees in C in April = 25/100 * 7840 = 1960
Required ratio = 3480:1960
= 87:49
Directions (6-10) :
6) Answer: C
Total number of ECE boys in D = 3/7 * 70/100 * D = 0.3D
Total number of ECE boys in B = 4/13 * 65/100 * B = 0.2B
Total number of CSE girls in B = 3/5 * 35/100 * B = 0.21B
Total number of CSE girls in D = 1/3 * 30/100 * D = 0.1D
0.3D – 0.2B = 14
0.21B – 0.1D = 24
D = 180
B = 200
Required average = (180 + 200)/2 = 190
7) Answer: D
Total number of students in D = x
Boys = 70/100 * x = 0.7x
Girls = 30/100 * x = 0.3x
Number of CSE boys in D = 0.7x * 4/7 = 0.4x
Number of ECE boys in D = 0.7x * 3/7 = 0.3x
Number of CSE girls in D = 0.3x * 1/3 = 0.1x
Number of ECE girls in D = 0.3x * 2/3 = 0.2x
0.3x – 0.2x = 18
x = 180
Difference = 0.4 * 180 – 0.2 * 180
= 36
8) Answer: D
Total number of students in A = x
Total number of CSE boys in A = 7/12 * 60/100 * x = 0.35x
0.35x = 140
x = 400
Total number of students in B = 400 * 125/100 = 500
Total number of CSE girls in B = 3/5 * 35/100 * 500 = 105
Total number of ECE girls in B = 2/5 * 35/100 * 500 = 70
Required percentage = 70/105 * 100 = 66.67%
9) Answer: A
Total number of students in C = x
Total number of students in F = y
Total number of CSE students in C = (1/3 * 50/100 * x) + (7/9 * 50/100 * x)
= 5x/9
Total number of CSE students in F = (3/8 * 75/100 * y) + (3/4 * 25/100 * y)
= 15y/32
5x/9 = 15y/32
x/y = 27/32 = 27: 32
