The average of six numbers is The average of two of them is 4, while the average of the other two is What is the average of the remaining two numbers?

A 4.5

B 4.6

C 4.7

D 4.8

Solution

Correct Answer: Option B

sum of six numbers = 6 x 3.95 =23.7

sum of two of them = 2 x 3.4 = 6.8

sum of other two = 2 x 3.85 =7.7

So Sum of four numbers = 14.5

So the remaining two numbers' sum = 9.2

Avg of the two = 4.6
