The sum of five numbers is 655. The average of the first two numbers is 78 and the third number is 108. Find the average of the remaining two numbers?
195.5
The sum of the five numbers is 655. The sum of the first two numbers = 78 × 2 = 156. The third number is 108. So, the sum of the remaining two numbers = 655 - (156 + 108) = 655 - 264 = 391. The average of the remaining two numbers = 391 / 2 = 195.5. Hence, the correct answer is 195.5.
