Multiple Choice question
The mean of 10, 12, 16, 20 ,p and 26 is 17 then the values of
P is
a)10
b) 16
c)17
d)18

Answer 1

Answer :

d) 18

Solution :

Here ,

The given observations are ;

10 , 12 , 16 , 20 , p , 26 .

Also ,

The mean of the given observations is 17 .

Also ,

We know that ,

Mean = (sum of observations)/(no. of observations)

Thus ,

=> 17 = (10 + 12 + 16 + 20 + p + 26)/6

=> 17 = (p + 84)/6

=> 17•6 = p + 84

=> 102 = p + 84

=> p = 102 - 84

=> p = 18

Hence p = 18 .

Answer 2

Given :

• The mean of 10, 12, 16, 20 ,p and 26 is 17

To Find :

• then the values of P is

Solution :

According to the Question :

(10 + 12 + 16 + 20 + 26 + p)/6 = 17

84 + p = 17 × 6

84 + p = 102

p = 102 - 84

p = 18

Hence the value of P is 18
