Question

if the mean of x, x+1,x+3,x+4 andx+7 is 25, find the value of x​

Answer 1

Step-by-step explanation:

Given the numbers x, x+1, x+3, x+4 and x+7

Their average is 25.

By the problem,

{x+(x+1)+(x+3)+(x+4)+(x+7)}= 25

or, x+x+1+x+3+x+4+x+7= 25

or, 5x+15= 25

or, 5x= 25-15

or, 5x = 10

i.e. x= 2
