Solutions:
1. E) Let’s assume that the total number of students passing the X examination is x.
There are 17000 students passing from Chennai in X exam,
20% of x = 17000
x = 85000
Number of students passing from Kolkata = 10% of 85000
the ratio of passed boys to passed girls in Kolkata is 9 : 8,
Number of boys passing from Kolkata = [9/(9 + 8)] of 10% of 85000 = (9/17) of 10% of 85000
Similarly, number of students passing from Hyderabad = 8% of 85000
the ratio of passed boys to passed girls in Hyderabad is 12 : 13,
Number of boys passing from Hyderabad = [12/(12 + 13)] of 8% of 85000 = (12/25) of 10% of 85000
Difference between the number of boys passing from Kolkata and Hyderabad
= (9/17) of 10% of 85000 – (12/25) of 10% of 85000
= 9/17 × 10/100 × 85000 – 12/25 × 10/100 × 85000
= 4500 – 3264 = 1236
2. B) Total number of students passing in class X exam = 120000
Number of passed students in the remaining part of the country = 25% of 120000
= (25/100) × 120000 = 30000
the ratio of passed boys to passed girls in the remaining part of country is 5 : 9,
Number of boys passing in class X exam in rest part of the country = 5/(5+9) of 30000
= (5/14) × 30000 = 10714 ≈ 10720
3. B) Let’s assume that the total number of students passing the XII examination is x.
Number of students passing from Chennai = 18% of x
the ratio of boys to girls passing the XII examination is 9 : 7 in Chennai,
number of boys passing from Chennai = 9/(9+7) of 18% of x = (9/16) of 18% of x
Similarly, number of students passing from Delhi = 16% of x
the ratio of boys to girls passing the XII examination is number of boys passing from Chennai = 3/(3+5) of 16% of x = (3/8) of 16% of x
According to the information given in the problem, the difference between the number of boys passing from Chennai and that from Delhi in XII exam is 3630.
(9/16) of 18% of x (3/8) of 16% of x = 3630
[(9/16 × 18) – (3/8 × 16)] × x/100 = 3630
(81/8 – 6) × x = 3630 × 100
33/8 × x = 363000
x = 363000 × (8/33)
x = 88000
4. D) Let’s assume that the total number of students passing the X examination is y.
 City Percentage of students passing from that city (a) Number of students passing from a city (b = a% of y) Ratio of boys to girls in a city (p:q) Number of girls passing from a city =q/(p+q)×b Ratio of girls to total students (b/y) Delhi 18 0.18y 2 : 3 0.108 y 0.1080 Mumbai 12 0.12y 4 : 7 0.0764 y 0.0764 Chennai 20 0.2y 13 : 11 0.0917 y 0.0917 Rest 25 0.25y 5 : 9 0.1607 y 0.1607 Hyderabad 8 0.08y 12 : 13 0.0416 y 0.0416
Clearly, the ratio of Number of girls passing with respect to total number of students is the maximum in other states.
5. C) Let’s assume that the total number of students from all the states is x.
Number of students passing class XII from Mumbai = 15% of x
9000 = 15% of x = 0.15 × x x = 60000
Now, number of students passing from Delhi in the same exam = 16% of 60000
= (16/100) × 60000 = 9600
Ratio of boys and girls passing from Delhi in this exam is 3 : 5,
Number of girls passing from Delhi in the same exam = 5/(5 + 3) × 9600 = 6000
(6 – 10):
Total number of players = 1000
Since ratio between female and male players is 3 : 7
Number of female players =3/10 × 1000 = 300
Number of male players = 1000 - 300 = 700
Since 25% of the total players are in Cricket
Number of cricket players = 25% of 1000 = 250
Since 28 per cent of cricket players are female
Number of female cricket players = 28% of 250 = 70
Number of male cricket players = 250 - 70 = 180
Number of Badminton players = 112
Since number of male badminton players is one fifth of male cricketers,
Number of male badminton players = 180/5 = 36
Number of female badminton players = 112 - 36 = 76
Since 30 per cent of the total players are in Chess,
Number of Chess players = 30% of 1000 = 300
Number of Basketball players =100/56 × 112 = 200
Since 50% of total badminton players is equal to number of female players in Basketball,
Number of female Basketball players = 50% of 112 = 56
Number of male Basketball players = 200 - 56 = 144
Since remaining players are in Kabaddi,
Number of Kabaddi players = 1000 - (250 + 112 + 300 + 200)
1000 - 862 = 138
Number of female Kabaddi players = 76/2 = 38
Number of male Kabaddi players = 138 - 38 = 100
Clearly, Number of female Chess players
= 300 - (70 + 76 + 56 + 38) = 60
Number of male Chess players = 300 - 60 = 240
6. B) Required percentage = 56/100 × 100 = 56%
7. A) The required difference = males in Chess - Males in Kabaddi = 240 - 100 = 140
8. D) In Badminton female players are maximum and male players are minimum as well.
9. B) total number of males in Basketball, Cricket, Chess and Kabaddi together = 144 + 180 + 240 + 100 = 664
10. B) required ratio = female Basketball players : male Badminton players = 56 : 36 = 14 : 9
