7. C (3km 50 m = 3km + 50/1000) 1km=1000m
8. C (n-2)x180
9. A ((n-2)x180)/n to find what is the degree for P
10. B
11. C (perpendicular = 90)
12. C (x=J)
13. D (5EL+100cm = 310)
14. C (area for trapezium = 1/2 x (2 parallel line)x height <10cm> )
15. D (meeting point for STQ and PR)
16. A (Use formula for triangle with perpendicular angle)
17. B (must have 6 rectangle for hexagon and one top and one bottom hexagon)
18. D (x=PSR ; PQR+PSR=180)
19. A (POQ= UOS ; POQ+UOS+ 155+y=360)
20. B (perimeter of a circle is 2 pie r)
21. A (PUT and QRS is a perfect circle; circumference of a circle= 2 pie r)
22. D (ST= 7cm x 2; Area of a arc = angle/360 x pie r^2)
23. B (ratio 10:25 )
24. C (pyramid = 1 surface; Cylinder with circle bottom= 2 surfaces)
25. C (PQR- 2 ; PQ=4cm using perpendicular triangle formula)
26. A (Question required volume that not filled with water)
27. B (black dotted mean larger or smaller with equal; white dotted mean larger or smaller without equal)
28. B (k= -6/2=-3 , substitute k=-3 into the equation of 3k-4m=-5 )
29. C (x:y=5:7, x+y= 12; x+y=48 as per question then use 48/12=4 mean the real is 4 times of ratio)
30. D (first hour =RM2, another 5 1/2 hours change it to 6 times of 1/2 hour so 6 x 1.50)
31. C (what is the distance? 105km/h x 3 hour = 315 km; 315km/(3 hour+extra 1/2 hour<30 minutes>) )

39. D (coordinate x for point R = 3)
40. B (distance = square root of ((x1-x2)^2 + (y1-y2)^2)
