Answers :

1) Answer: B

Percentage of girls in school A = 100 – 55 = 45%

Number of girls in school A = 45/100 x 1500 = 675

Number of girls in school D = 65/100 x 2000 = 1300

Required percentage = 675/1300 x 100 = 51.92%

2) Answer: C

Percentage of girls of school E = (100 – 70) = 30%

Number of girls of school E = 30/100 x 3500 = 1050

Number of girls of school B = 40/100 x 2500 = 1000

Required percentage = [(1050 – 1000)/1000] x 100 = 50/1000 x 100 = 5%

3) Answer: D

Number of boys of school C = 5/6 x 1800 = 1500

Number of boys of school D = 35/100 x 2000 = 700

Required sum = 1500 + 700 = 2200

4) Answer: A

Number of girls of school B = 40/100 x 2100 = 840

Number of girls of school A = (100 – 55)/100 x 1500 = 675

Required ratio = 840 : 675 = 56 : 45

5) Answer: B

Strength of schools A and C together = 1500 + 1800 = 3300

Required percentage = [(3300 – 2000)/2000] x 100 = 65%

6) Answer: B

15120/7 = 2160

2160/6 = 360

360/5 = 72

72/4 = 18

18/3 = 6

7) Answer: E

64 * 6.5 = 416

416 * 5.5 = 2288

2288 * 4.5 = 10296

10296 * 3.5 = 36036

36036 * 2.5 = 90090

8) Answer: D

4² + 10 = 26

5² + 15 = 40

6² + 20 = 56

7² + 25 = 74

8² + 30 = 94

9² + 35 = 116

9) Answer: A

3 * 9 + 1 = 28

28 * 7 + 1 = 197

197 * 5 + 1 = 986

986 * 3 + 1 = 2959

2959 * 1 + 1 = 2960

10) Answer: D

1 * 11 = 11

3 * 12 = 36

5 * 13 = 65

7 * 14 = 98

9 * 15 = 135
