1. D
First arrange the numbers in a numerical sequence: 1,2,3,4,5,6,7,8,9, 10. Then find the middle number or numbers. The middle numbers are 5 and 6. The median = 5 + 6/2 = 11/2 = 5.5

2. B
First arrange the numbers in a numerical sequence: 3,7, 17, 19, 20, 21, 31, 43, 46. Next find the middle number. The median = 20

3. A
First arrange the numbers in a numerical sequence: 29,100, 200, 300, 450, 1029, 2001. Next find the middle number. The median = 300

4. B
Simply find the most recurring number. The most occurring number in the series is 9

5. D
Simply find the most recurring number. The most occurring number in the series is 90.

6. C
Simply find the most recurring number. The most occurring number in the series is 17.

7. B
First add all the numbers 100 + 1050 + 320 + 600 + 150 = 2220. Then divide by 5 (the number of data provided) = 2220/5 = 444

8. A
First add all the numbers 3 + 6 + 27 + 13 + 6 + 8 + 12 + 20 + 5 + 10 = 110. Then divide by 10 (the number of data provided) = 110/10 = 11

9. D
First add all the numbers 62 + 18 + 39 + 13 + 16 + 37 + 25 = 210. Then divide by 7 (the number of data provided) = 210/7 = 30
