As we know average is the sum of all the numbers divided by the total number.
So 10 + 20 + 30 + 40 + x / 5 = 60
100 + x / 5 = 60
100 + x = 300
x = 300 - 100
x = 200

Given:
Numbers given = 10 , 20 , 30 , 40 , x
Aritmetic mean AM = 60
To Find:
Find the value of x
Solution:
We know,
AM = sum of numbers/ total numbers
60 = (10+20+30+40+x)/5
100+x=300
x=300-100
x=200
Hence the value of x is 200
