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?

Correct option is A

Given:

The sum of five numbers is 655.

The average of the first two numbers is 78.

The third number is 108.

Formula used:

Sum of numbers = Average × Number of terms

Solution:

Sum of first two numbers = 78 × 2
Sum of first two numbers = 156

Sum of remaining two numbers = Total sum - Sum of first two numbers - Third number

Sum of remaining two numbers = 655 - 156 - 108
Sum of remaining two numbers = 391

Average of remaining two numbers =$$\frac{\text{ Sum of remaining two numbers }}{\text{ Number of terms}}$$

​​Average of remaining two numbers =$$\frac{391}2$$= 195.5​
