The sum of five numbers is 655. The average of the first two numbers is 75 and the thirdnumber is 128. Find the average of the remaining two numbers?

Correct option is A

Given:

Sum of five numbers = 655

Average of first two numbers = 75 

Third number = 128

Formula Used:

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

Solution: 

Sum of first two number = 75 × 2 = 150

Sum of first 3 numbers = 150 + 128 = 278

Remaining sum = 655 − 278 = 377

Average of remaining 2 numbers = $$\frac{377}{2}$$​ = 188.5
