Question

the mean of the following set of numbers is 6 and the mode is 8. Find the value of x and y

4,8,6,x,9,5,y

Answer 1

Mean)= no. Of observations / total no of observations
32+x+y/7=6
32+x+y=6*7
x+y=42-32
x+y=10(i)

Mode is the most repeated number., therefore y=8
x+y=10
x+8=10
x=2


X=2,y=8
