The sum of five numbers is 655. The average of the first two numbers is 78 and the third number is 115. Find the average of the remaining two numbers?

Correct option is C

Given:

Sum of 5 numbers = 655

Average of first two numbers = 78

Third number = 115

Find: Average of remaining two numbers

Formula Used:

Average = $$\frac{\text{Sum of values}}{\text{Number of values}}$$​​

Solution:

Sum of first three numbers = 156 + 115 = 271

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

Sum of last two numbers = 655 - 271 = 384

Average of last two numbers = 384 ÷ 2 = 192
