Question

Given that the average of six numbers is 3.95 and the average of first two numbers and last two numbers is 3.4 and 3.85 respectively. What is the average of the remaining two numbers?

• A. 4.2
• B. 4.7
• C. 4.6
• D. 4.8

Answer 1

The correct option is C

4.6

Sum of remaining two numbers = (3.95 x 6) – (3.85 x 2) – (3.4 x 2) = 23.70 – 14.5 = 9.20

$\therefore$ Average of these two numbers = (9.2/2) = 4.6
