Solution:
1). The series is ×4 and ×7/10 alternately.
2). The series is ×8 – 28, ×7 – 24, ×6 – 20, ×5 – 16, ...
3). The series is ×1 + 1 ×5, ×2 – 2 ×7, ×3 + 3 ×9, ×4 – 4 × 11, ....
4). The series is ×1- 22 , ×2+12 , ×3- 22 , ×4+12 , ...
5). The series is ×1.5 + 1.5, ×2 + 2, ×2.5 + 2.5, ×3 + 3, ....

6). The percentage of Engineering graduates employees and Arts graduate employees in TCS company = (100 – 32) % = 68%
Now, the percentage of Arts graduate employees = 68 × 7 / 17 = 28%
The percentage of Engineering graduates employees = 68 × 10 / 17 = 40%
The number of Arts graduate employees in TCS company = 1050 × 28 / 100 = 294

7). Total number of employees in HCL company = 700
Percentage of IT graduates employees = [100 – (31+40)] = 29%
Now, the percentage difference between Arts graduate employees and IT graduates employees = (40 – 29) % = 11%
11% of 700 = 77
Difference = 77

8). The number of employees in HCL company in December 2015 = 700
The number of employees in HCL company in December 2016 = 700 × 120 / 100 = 840
Number of IT graduates employees in HCL company in December 2016 = 20 × 840 / 100 = 168

9). The percentage of Arts graduate employees in HP company = (100-35-50) % = 15%
Now, the percentage of Arts graduate employees and Engineering graduates employees = 50 + 15 = 65%
Average of Commerce and Arts graduate employees = 312
The total number of employees in Commerce and Arts = 2 × 312
Let the total employees in HP company be x. Then, 65% of x = 2 × 312
X = 2 × 312 × 100 / 65 = 960

10). The percentage of Arts employees in GMK company = (100 – 30 – 30) = 40%
The percentage difference between Arts graduate employees in GMK company and TVS Company = (40 – 20) = 20%
Now, let the number of employees in GMK company be x.
Then, x × 20% = 180
X= 180 × 100 / 20 = 900.
