Question

1. Figures; 10, 50, 70, 20, 95. Median is
(a) 20
(b) 50
(c)70
(d) None of the above​

Answer 1

Answer:

b) 50

Explanation:

Ascending Order= 10,20,50,70,95

Number of digits= 5

Formula when the number of digits is odd = (n+1 )/2

Therefore, = 5+1/2

=3

3rd digit= 50 (According to ascending order)

Answer 2

The median of 10,50,70,20,95 is 50.

Option (b) is correct.

Given:

• 10,50,70,20,95

To find:

• Find the median of given data.
• (a) 20
• (b) 50
• (c)70
• (d) None of the above.

Solution:

Step 1:

Arrange the numbers in ascending order.

$\bf 10, \: 20, \: 50, \: 70, \: 95$

Step 2:

Find the median of given numbers.

Total numbers are (n)= 5

When n is odd, then the median of a given data is$\left( {\frac{n + 1}{2}} \right)^{th}$ number.

Here,

$\left( {\frac{5 + 1}{2}} \right)^{th}$

i.e.

${3}^{rd} \:$ data is median.

Third data is 50,

Thus,

Median of data is 50.

Option (b) is correct.
