Answers :
Directions (1-5) :
1) Answer: D
Total colour bottles manufactured by company P = 24000 * 15/100 * 80/100
= 2880
Total number of pink colour bottles manufactured by company P
= 2880 * (3/12) = 720
2) Answer: C
Total colour bottles manufactured by company R = 24000 * 12/100 * 60/100
= 1728
Total plain bottles manufactured by company S = 24000 * 18/100 * 10/100
= 432
Required percentage = 1728/432 * 100
= 400%
3) Answer: A
Total number of plain bottles manufactured by company Q
= 24000 * 20/100 * 25/100
= 1200
Total number of plain bottles manufactured by company U
= 24000 * 15/100 * 30/100
= 1080
Required ratio = 1200: 1080
= 10: 9
4) Answer: E
Total bottles manufactured by company T = 24000 * 20/100 = 4800
Number of plain bottles manufactured by company T = 4800 * 50/100
= 2400
Number of colour bottles manufactured by company T = 4800 * 50/100
= 2400
Required probability = 2400C1Â * 2400C1/4800C2
= (2400 * 2400)/(4800 * 4799/1*2)
= 2400/4799
5) Answer: D
Total plain bottles manufactured by company P = 24000 * 15/100 * 20/100
= 720
Total plain bottles manufactured by company Q = 24000 * 20/100 * 25/100
= 1200
Total plain bottles manufactured by company R = 24000 * 12/100 * 40/100
= 1152
Total plain bottles manufactured by company S = 24000 * 18/100 * 10/100
= 432
Total plain bottles manufactured by company T = 24000 * 20/100 * 50/100
= 2400
Total plain bottles manufactured by company U = 24000 * 15/100 * 30/100
= 1080
Required average = (720 + 1200 + 1152 + 432 + 2400 + 1080)/6
= 6984/6 = 1164
Directions (6-10) :
6) Answer: D
The pattern is as follows:
26 * 3 = 78
78 * 4 = 312
312 * 5 = 1560
1560 * 6 = 9360
9360 * 7 = 65520
7) Answer: D
The pattern is shown below:
31 + 4 * 1 = 35
35 + 4 * 3 = 47
47 + 4 * 5 =67
67 + 4 * 7 = 95
95 + 4 * 9 = 131
8) Answer: B
The pattern is as follows:
5979 – 64 = 5915
5915 – 100 = 5815
5815 – 144 = 5671
5671 – 196 = 5475
5475 – 256 = 5219
9) Answer: B
The series is as follows:
103Â + 2 = 1002
113Â + 3 = 1334
123Â + 4 = 1732
133Â + 5 = 2202
143+ 6 = 2750
153Â + 7 = 3382
10) Answer: A
959 + 92Â = 1040
1040 + 132Â = 1209
1209 + 172Â = 1498
1498 + 212Â = 1939
1939 + 252Â = 2564
