The mean of 6 number is 6.5 and its variance is 10.25 . If 4 numbers are 2,4.5 and 7 , then find the other two

The mean of 6 distinct observations is 6.5 and their variance is 10.25. If 4 out of 6 observations are 2, 4,5 and 7, then remaining two observations are :

The mean of the number a,b,8,5,10 is 6 and the variance is 6.80 . Then ab =

The mean of five observations is 4 and their variance is 5.2. If three of these observations are 2, 4 and 6, then the other two observations are :

The means of five observations is 4 and their variance is 5.2. If three of these observations are 1,2 and 6, then the other two are 2 and 9 (b) 3 and 8 4 and 7 (d) 5 and 6
