Answer 2

Arrange the data in ascending order .

20, 50, 70, 30, 45, 35, 15, 75, 90, 20

In ascending we have :

15

20

20

30

35

45

50

70

75

90

Number of observations = 10

Find the median .

Median = ( n / 2 th + n / 2 th + 1 th observation ) / 2

= > ( 10 / 2 th + 10 / 2 + 1 th ) / 2

= > ( 5 th obs + 5 th + 1 th obs ) / 2

= > ( 5 th obs + 6 th obs ) / 2

= > ( 35 + 45 ) / 2

= > 80 / 2

= > 40

ANSWER :

40
