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
tablecricket, 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
