Verified Answer
The average of six numbers is 3.95. The average of two of them is 3.4,...
Sum of the remaining two numbers = (3.95 x 6) - [(3.4 x 2) + (3.85 x 2)]
= 23.70 - (6.8 + 7.7) = 23.70 - 14.5 = 9.20
Required average = (9.2/2) = 4.6
= 23.70 - (6.8 + 7.7) = 23.70 - 14.5 = 9.20
Required average = (9.2/2) = 4.6

The average of six numbers is 3.95. The average of two of them is 3.4,...
To find the average of the remaining two numbers, we need to find their sum and divide it by 2. Let's denote the six numbers as a, b, c, d, e, and f.
Given information:
Average of the six numbers = 3.95
Average of two numbers (a and b) = 3.4
Average of two numbers (c and d) = 3.85
Finding the sum of all six numbers:
Sum of the six numbers = Average of the six numbers × Total number of numbers
Sum of the six numbers = 3.95 × 6 = 23.7
Finding the sum of the first two numbers (a and b):
Sum of the first two numbers = Average of the first two numbers × Total number of numbers
Sum of the first two numbers = 3.4 × 2 = 6.8
Finding the sum of the next two numbers (c and d):
Sum of the next two numbers = Average of the next two numbers × Total number of numbers
Sum of the next two numbers = 3.85 × 2 = 7.7
Finding the sum of the remaining two numbers (e and f):
Sum of the remaining two numbers = Sum of all six numbers - Sum of the first two numbers - Sum of the next two numbers
Sum of the remaining two numbers = 23.7 - 6.8 - 7.7 = 9.2
Finding the average of the remaining two numbers:
Average of the remaining two numbers = Sum of the remaining two numbers ÷ Total number of numbers
Average of the remaining two numbers = 9.2 ÷ 2 = 4.6
Therefore, the average of the remaining two numbers is 4.6, which corresponds to option B.
Given information:
Average of the six numbers = 3.95
Average of two numbers (a and b) = 3.4
Average of two numbers (c and d) = 3.85
Finding the sum of all six numbers:
Sum of the six numbers = Average of the six numbers × Total number of numbers
Sum of the six numbers = 3.95 × 6 = 23.7
Finding the sum of the first two numbers (a and b):
Sum of the first two numbers = Average of the first two numbers × Total number of numbers
Sum of the first two numbers = 3.4 × 2 = 6.8
Finding the sum of the next two numbers (c and d):
Sum of the next two numbers = Average of the next two numbers × Total number of numbers
Sum of the next two numbers = 3.85 × 2 = 7.7
Finding the sum of the remaining two numbers (e and f):
Sum of the remaining two numbers = Sum of all six numbers - Sum of the first two numbers - Sum of the next two numbers
Sum of the remaining two numbers = 23.7 - 6.8 - 7.7 = 9.2
Finding the average of the remaining two numbers:
Average of the remaining two numbers = Sum of the remaining two numbers ÷ Total number of numbers
Average of the remaining two numbers = 9.2 ÷ 2 = 4.6
Therefore, the average of the remaining two numbers is 4.6, which corresponds to option B.
