1. ( B ) 11 + 12 + 13 + 14 + 15 + 16 + 17 + 18 + 19 = 135
2. ( D ) 1 23 1+2+3=6
1
1+2=3
2 Total : 6 x 3 = 18
3. ( A ) 7 + 2 = 9, 9 + 1 = 10
4. ( C ) 20 Odd number from 1-40 : 1,3,5,7,9,11,13,15,17,19,
21,23,25,27,29,31,33,35,37,39
5. ( D ) 65 + 23 + 87 - (62 + 83 + 21)
= 65 + 23 + 87 - 62 - 83 - 21
= (65-62) + (23-21) + (87-83)
=3+2+4
=9
6. ( D ) X = 22, Y = 21, X + Y = 22 + 21 = 43
7. ( C ) Cubes that can be seen = 12
Cubes that can be seen = 6
Total cubes = 12 + 6 = 18
8. ( C ) Big Square = 4, Tiny square = 1, total sqaures = 4 + 1 = 5
9. ( C ) To get the 2nd image, the 1st image is rotated anticlockwise
and the right side is shaded.
Therefore, is the
answer.
10. ( D ) 10 + 21 = 31. Therefore, the number fill into the box must be
smaller than 31. Hence, 20 ( D ) is the only answer.
11. ( A ) 169 + 23 + A = 291. Hence, A = 291 -169 - 23 = 99
12. ( E ) Given X is an odd number, 21 must add a even number to get
an odd number. 4 ( E ) is the only odd number.
13.( A ) 2 + 12hr = 14
14 - 8hr = 6 o’clock
14. ( D ) 1 + 4 + 8 = 13
15. ( D ) 2 x 60 + 30 = 150 minutes
16. ( B )
17. ( D )
All the series are +2, except for ( D ) which the difference
between 1st and next number is 4
18. ( B ) (7 + 5) + (12 + 5) = 29
19. ( E ) X = 28 + 3 = 31
Y = 35 + 3 = 38, X - Y = 38 - 31 = 7
20. ( A ) A = 3/4 B = 1/2 C = 1/2 D = 3/16
3/4 is the biggest, therefore A is the answer
21. ( D ) Joe / Rafi / are the first winner.
22. ( B ) They run 1 round 1 day. Hence, 3 days they run 1 x 3 = 3 rounds
23. ( B ) 7 people in front of him + Himself + 2 people at his back -
2 people who left. 7 + 1 + 2 - 2 = 8
24. ( D )10 x 20 = 200
25. ( D ) ( 10 - 2 ) ÷2
