Question

The numbers 3, 7, 13, 14, 16, 19, 20 and x are arranged in ascending order. If the mean of the numbers is equal to the median, find the value of x. *

Answer 1

Step-by-step explanation:

3,7,13,14,16,19,20,x

according to question

mean=median

so that median=total no.÷2(even no.)

=8÷2

=8/2

=4th no.

=14

therefore mean=total no.of addition/total no.

14 =3+7+13+14+16+19+20+x/8

14×8 =92+x

112 =92+x

so, x =112-92

x =20 Ans.
