Question

The average of eight numbers is 4.6. The average of three of them is 4.2, while th average of other three is 4.4 what is th average of the remaining two numbers?

Answer 1

Answer:

Average of 8 = 4.6

Then sum = 8×4.6 = 36.8

Average of 3 = 4.2

Sum = 3×4.2 = 12.6

Average of another 3 = 4.4

Sum = 3× 4.4 = 13.2

Then average of 2 = [ 36.8 - ( 12.6 + 13.2 ) ] ÷ 2 = 5.5

Answer 2

Answer:

5.5

Step-by-step explanation:

average of 8 numbers = 4.8

then sum = 4.6×8 =

average of 3 of them = 4.2

then sum = 4.2×3 = 12.6

average of other 3 of them = 4.4

then sum = 4.4×3 = 13.2

average of remaining 2 numbers = x

x = [36.8-(12.6+13.2)]/2

x = [36.8-25.8]/2

x = 11.0/2

x = 11/2 = 5.5
