Question

plz solve 8th and 10th question .......I am having confusion .....

Answer 1

8)Given:
x+x+2+x+4+x+6+x+8/5 = 24
x+x+2+x+4+x+6+x+8 = 24*5 =120
5x+20 = 120
5x=100
x=20

10) Mean of 6 = 24
Sum total of 6 = 24*6 = 144
when 1 number is excluded, the mean is 22
sum total of 5 numbers = 22*5 =110
So,excluded number = 144-110=34

Answer 2

X + X + 2 + x + 4 + x + 6 + x + 8 / 5 equal to 24 5 x + 20 / 5 equal to 24
X + 4 equal to 24
X equal to xx

mean of 5 numbers divided by 5 equal to 22
mean of 5 numbers equal to 5 X 22 equal to 110
mean of 5 numbers + 6th number / 6 equal to 24
let 6th number b e x
now 110 plus x / 6 equal to 24
110+x=24×6=84
x=84-110
x=-36
