Answers :
Direction (1-5) :
1) Answer: d)
4 * 1 + 2 = 6
6 * 2 + 3 = 15
15 * 3 + 4 = 49
49 * 4 + 5 = 201
201 * 5 + 6 = 1011
1011 * 6 + 7 = 6073
2) Answer: b)
The pattern of the series is +14, +28, +42, +56…………
3) Answer: c)
6754 – 25 = 6729
6729 – 49 = 6680
6680 – 81 = 6599
6599 – 121 = 6478
6478 – 169 = 6309
6309 – 225 = 6084
4) Answer: a)
The pattern of the series is + 42, + 82, + 122, + 162, + 202, + 242
5) Answer: d)
The pattern of the series is *4, *5, *6,*7……………
Direction (6-10) :
6) Answer: b)
In 2015, Number of students in branch B= 280 and Number of students in branch C = 150
Hence required percentage = [(280 – 150)/150] * 100
= 86.67%
7) Answer: e)
Total number of students in branch A from 2016 to 2018 = 125 + 170 + 110
= 405
Total number of students in branch C from 2014 and 2016 = 225 + 220
= 445
Required ratio = 405: 445
= 81: 89
8) Answer: d)
Percentage change for branch A in the year 2018 compared to 2017
= [(170 – 125)/170] * 100
Percentage change for branch C in the year 2018 compared to 2017
= [(250 – 200)/250] * 100
= 26.47%
Required difference = 26.47 – 20 = 6.47%
9) Answer: d)
Total number of students in 2019 = (110% of 180) + (112.5% of 200) + (115% of 220)
= 198 + 225 + 253
= 676
Now total students in 2017= 170 + 150 + 250
= 570
Thus required difference = 676 – 570
= 106
10) Answer: b)
Number of students in branch B in the year 2017 = 150
And Number of students in branch B in the year 2016 = 125
Thus required percentage change = [(150 – 125)/125] * 100
= 20%
