Solutions:
1. C) Total number of employees in Company N = 700
Percentage of Science graduate employees = [100 – (31 + 40)] = 29%
Now, the percentage difference between Arts graduate employees and Science graduate employees =(40 – 29)% = 11%
11% of 700 = 77
Difference = 77

2. B) The percentage of Arts graduate employees in Company Q = (100 – 35 – 50)% = 15%
Now, the percentage of Arts graduate employees and Commerce graduate 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 Company Q be x.
Then, 65% of x = 2 ×312
x = (2 × 312 × 100) / 65 = 960

3. A) The percentage of Commerce graduate employees and Arts graduate employees in Company M = (100 – 32)% = 68%
Now, the percentage of Arts graduate employees = (68 × 7) / 17 = 28%
The percentage of Commerce graduate employees = (68 × 10) / 17 = 40%
The number of Arts graduate employees in Company M = (1050 × 28) / 100 = 294

4. E) The number of employees in Company N in December 2012 = 700
The number of employees in Company N in December 2013 = (700 × 120) / 100 = 840
Number of Science graduate employees in Company N in December 2013 = (20 × 840) / 100 = 168

5. D) The percentage of Arts employees in Company O = (100 – 30 – 30) = 40%
The percentage different between Arts graduate employees in Company O and P = (40 – 20) = 20%
Now, let the number of employees in Company O be x.
Then, x × 20% = 180
x = (180 × 100) / 20 = 900

(6 – 10): Explanation:
Number of female players = 1000 × (2/5) = 400
Number of male players= 1000 × (3/5) =600
Let the number of Rugby players be x.
Then, the number of Cricket players will be 2x.
According to the question,
x + 2x = 1000 – (200 + 150 + 80)
Or, x =190

6. D) Reqd difference = 266 – 116 = 150

7. D) Reqd % = (120/40) ×100 = 300%

8. C) Total number of female players in Polo, Rugby and TT = (40 + 50 + 116) = 206

9. B) Reqd ratio = (40/80) = 1:2

10. A) Reqd % = (380/1000) × 100 = 38%

11. D) Total number of students playing cricket = 38 + 40 + 12 + 17 + 25 + 18 + 20 = 170
Required percentage = (25 / 170) × 100 = 14.706 = 15

12. D) Required ratio = 27 : 18 = 3 : 2

13. E) For calculating the most popular game we have to add students playing different games of all the classes.
By looking at the table-cricket, football and badminton seems to be very popular. No. of students playing chess is definitely less than those playing cricket. Same is true for basketball. Table tennis carom, and tennis
Badminton and football may be somewhat near to cricket
No of students playing cricket = 38 + 40 + 12 + 17 + 25 + 18 + 20 = 170
No of students playing football = 40 + 27 + 18 + 19 + 12 + 16 + 14 = 146
No of students playing badminton = 47 + 39 + 33 + 21 + 19 = 159
Thus, cricket is the most popular game

14. E) Total number of students of class X playing different games
= 5 + 12 + 7 + 21 + 18 + 8 + 11 + 33 = 115
Required percentage = (21 / 115) × 100 = 18.26 = 18

15. E) Check from given options
Option (a) Basket ball only
Option (b) Badminton only. Even badminton has ascending number of students from Class IX to XII
Hence
Option (e) is correct because we do not have any answer choice with both basketball and badminton
