Answers :
1) Answer: A
Number of employees in ICICI = 10/3 * 3600 = 12000
Number of employees in PNB = 7/3 * 3600 = 8400
Number of clerk in ICICI = 12000 * 30/100 = 3600
Number of clerk in PNB = 8400 * 28/100 = 2352
Difference = 3600 – 2352 = 1248
2) Answer: B
Number of employees in PNB = 100x
Number of specialist in PNB = 15/14 * 28 = 30%
Number of PO in PNB = 100x * (100 – 28 – 30)/100 = 42x
Number of employees in SBI = 100y
Number of PO in SBI = 100y * (100 – 30 – 25)/100 = 45y
42x/45y = 28/15
x/y = 2/1
100x + 100(x/2) = 7200
x = 48
Number of employees in SBI = 48/2 * 100 = 2400
Number of employees in PNB = 48 * 100 = 4800
Specialist in PNB = 4800 * 30/100 = 1440
Specialist in SBI = 2400 * 25/100 = 600
Difference = 1440 – 600 = 840
3) Answer: A
Number of employees in ICICI = 6x
Number of employees in BOB = 7x
6x * 34/100 * 80 = 97920
x = 600
Number of PO in ICICI = 600 * 6 * 36/100 = 1296
Number of PO in BOB = 600 * 7 * 40/100 = 1680
Difference = 1680 – 1296 = 384
4) Answer: C
Number of employees in SBI = 2x
Number of employees in HDFC = 2x * 150/100 = 3x
Number of clerk in HDFC = 3x * (100 – 45 – 20)/100 = 1.05x
Number of clerk in SBI = 2x * 30/100 = 0.6x
0.6x + 1.05x = 3630
x = 2200
Number of specialist in SBI = 2200 * 2 * 25/100 = 1100
Number of specialist in HDFC = 2200 * 3 * 20/100 = 1320
Required sum = 1100 + 1320 = 2420
5) Answer: D
Number of employees in BOB = 100x
Total number of employees in HDFC = 100x * 180/100 = 180x
Number of male PO employees in BOB = 5/8 * 40/100 * 100x = 25x
Number of female PO employees in HDFC = 180x * 45/100 * 4/9 = 36x
Required percentage = 25x/36x * 100
= 69.44%
6) Answer: D
Total number of passenger in S1 = 400
Number of female passengers in S1 = 30 * 750/100 = 225
Number of male passengers in S1 = 400 – 225 = 175
Total number of passengers in S2 = 200
Number of female passengers in S2 = 18/100 * 750 = 135
Number of male passengers in S2 = 200 – 135 = 65
Total number of passengers in S3 = 100
Number of female passengers in S3 = 10/100 * 750 = 75
Number of male passengers in S3 = 100 – 75 = 25
Total number of passengers in S4 = 250
Number of female passengers in S4 = 22/100 * 750 = 165
Number of male passengers in S4 = 250 – 165 = 85
Total number of passengers in S5 = 300
Number of female passengers in S5 = 20/100 * 750 = 150
Number of male passengers in S5 = 300 – 150 = 150
Required ratio = (175 + 65):(75 + 165)
= 240:240
= 1:1
7) Answer: A
Required percentage = (25 + 85)/(100 + 250) * 100
= (110/350) * 100
= 31.43%
8) Answer: B
Required difference = (225 + 150) – (65 + 25 + 85)
= 375 – 175
= 200
9) Answer: D
Required percentage = (285-240)/240* 100
= (45/240) * 100
= 18.75%
10) Answer: E
Number of male passengers in S6 = 140/100 * 150 = 210
Number of female passengers in S6 = 210 * 150/100 = 315
Total number of passengers in S6 = 210 + 315 = 525
