Question

11. The mean of x+8, x+6,x+4,x+2 and x is 24 . Find the value of x.

​

Answer 1

Answer:

(x+8 + x+6 + x+4 + x+2 + x)/5 = 24

=> 5x + 20 = 24 × 5

=> 5x = 120-20

=> x = 100/5

=> x = 20. ans.....

Answer 2

Answer:

Since mean is the average of every no. given

so the step to calculate it is very easy we have to add each and every no. given and divide the total numbers given and the whole equal to mean

Step-by-step explanation:

So first we add all the numbers

x+8+x+6+x+4+x+2+x = 5x+20

Now total no. of numbers given are 5

And Mean =24

THEREFORE, (5X+20)/5 = 24

5X + 20 = 24×5

so 5x+20=120

5x=120—20

then. 5x=100

x=100/5

hence. x=20

hope the doubt is clear
