The sum of five numbers is 655. The average of the first two numbers is 77 and the third number is 128. Find the average of the remaining two numbers.​

Correct option is B

Given:

Sum of five numbers = 655;

Average of first two numbers = 77 

Third number = 128

Required: Average of the remaining two numbers.

Formula Used:

Average = $$\frac{\text{Sum of number}}{\text{count of numbers}}$$​​

Solution: 

Sum of first two numbers = 77 × 2 = 154

Sum of first three numbers  = 154 + 128 = 282

Sum of last two numbers = 655 - 282 = 373

Average = $$\frac{373}{2}$$​ = 186.5
