Question

If the mean of 5 values is 8.2 and 4 values are 6, 10, 7, and 12, what is the fifth value

Answer 1

Answer:

Mean = 8.2

Let the fifth value be 'x'

6+10+7+12+x/5=8.2

35+x/5=8.2

35+x=41

x=41-35

x=6

Hence the fifth value is 6

Answer 2

Answer:

6+10+7+12=35

8.2x5=41

41-35=6

5th value=6
