Hi I have 4 questions in exam in blue book please help me,since I have exam tomorrow :).

For question 6 I know how to do it but the problem is how can I do this fast instead of arranging all numbers and cancelling and getting the median ? Note: I replaced table with writing:

Score: Number of Students
100 1
95 2
90 4
85 1
80 3
75 2
70 2
65 0
60 1
I replaced Table with writing.
6)The scores on tuesday test for 16 students are shown in the table Above. Sam,who was the only student absent on Tuesday,will take the test next week. If Sam receives a score of 95 on the test, what will be the median score for the test?
1)90
2)87.5
3)85
4)82.5
5)80

Those are Grid In question:-

13)A company sells boxes of balloons in which the balloons are red,green,or blue. Luann purchased a box of balloons in which 1/3 of them were red. If there were half as many green balloons in the box as red ones and 18 balloons were blue,how many were in the box ?

17)Alice and Corine stand back to back. THey each take 10 steps in opposite directions away from each other and stop. Alice then turns around, walks toward Corine, and reaches her in 17 steps. The length of one of Alice’s steps is how many times the length of one of Corrine’s steps? Note(All of Alice’s steps are the same legnth and all Coriinne’s Steps are the same length).
