Question

45,60,63,x,x+2,75,85,100 if the median of the data is 69 find the value of x

Answer 1

Ans.

Given that
$\frac{45 + 60 +63 + x + (x + 2) + 75 + 85 + 100}{8} = 69$
or, 430 + 2x = 552
or, 2x = 122
or, x = 61

So the value of x is 61.

I HOPE THAT THIS HELPS YOU.

Answer 2

no. of observation=8
x+x+2+45+60+63+75+85+100=2x+430
median=69
ATP
(2x+430)/8=69
2x+430=69*8
2x+430=552
2x=552-430
2x=122
x=122/2
x=61
ans: x=61
