The following table shows the number of students of 7 colleges participating in extra curricular activities:


Read the table and answer questions 86 to 90.

The difference of the range of number of students in activity IV and the average of number of students in activity III per college is

  • 111

  • 153

  • 104

  • 217

Solution

C.

104

Range of number of students in activity IV
 = 438 - 105 = 333
Average number of students in activity III:
equals space fraction numerator 65 plus 130 plus 420 plus 75 plus 540 plus 220 plus 153 over denominator 7 end fraction equals space 1603 over 7 space equals space 229
∴  Required difference  = 333 - 229 = 104

The following table shows the number of students of 7 colleges participating in extra curricular activities:


Read the table and answer questions 86 to 90.

Percentage of the number of students in activity II to that of IV is

  • 37

  • 42

  • 48

  • 50

Solution

D.

50

Total number of students in activity II
 = 100 + 200 + 200 + 100 + 100 + 100 + 100 = 900
Total number of students in activity IV
= 317 + 155 + 438 + 105 + 385 + 280 + 120 = 1800
∴  Required percentage
   equals space 900 over 1800 cross times 100 space equals space 50

The following table shows the number of students of 7 colleges participating in extra curricular activities:


Read the table and answer questions 86 to 90.

The median of data pertaining to activity III is


  • 540

  • 229

  • 153

  • 75

Solution

C.

153

Arrange the observations of activity III in ascending order.
65, 75, 130, 153, 220, 420, 540
Number of observations  = 7 (odd)
∴   Median = open parentheses fraction numerator 7 plus 1 over denominator 2 end fraction close parentheses th space observation
 = Fourth observation  = 153
