Section B

16) Seventy - four thousand and fifty-two (0m for missing hyphens and wrong spelling)

17) 10050 - 10000 = 50

18) 55 989

19) 5 and 1/3

20) 3/5

21) 90 - 50 = 40 degrees

22) 64019, 60149, 41906, 41069

23) 7, 42 (1m each, if more than 2 answers, minus 1m for every wrong answer)

24) 4 x 12 = 48

25) 2000/ 4 = 500

26) 5/12 + 11/12 = 1 and 1/3

27) 1/4 = 2/8; shade any 2 circles

28) (0m for not labeling angle, -1m for not labeling Z)

29) 3

30) 4 - 2 = 2, 8 + 2 = 10

31) Line must be drawn through the point R, angle at pt R should be between 89 - 91 degrees.

32) Line must be drawn through W

33) 3

34) 8 x 8 = 64

20 x 8 = 160

6 x 6 = 36

64 + 160 +36 = 260 cm^2

35) CD and IJ or EF and IJ

Section C

36) Factors of 36 = 1, 2, 3, 4, 6, 9

Factors of 54 = 1, 2, 3, 6, 9

Common Factors = 1, 2, 3, 6, 9

Thus, answer is 6298

37a) 45 + 90 + 90 + 45 = 270

b) home

38) [ Draw Model]

300 + 300 + 630 = 1230

1230/3 = 410

410 + 1230 = 1640 ml

39) 1 unit -> 12

4 units -> 48

48 - 28 = 20

20/48 = 5/12

40) [draw model]

1 - 1/7 = 6/7

4 units -> 24

1 unit-> 6

7 units -> 6 x 7 = 42

41) 42 - 16 = 26

26 x 3 = 78

78 + 42 + 16 = 136

b) 42 + 16 = 58

136 - 58 = 78

42) 6 x 4 = 24

24 x 6 = 144

144 = 12 x 12 cm

43) 405 / 5 = 81

81 = 9 x 9

9 x 5 = 45 ( Length of rect Y)

9 x 3 = 27 ( Breadth of rect Y)

Area = 45 x 27

= 1215 cm^2
