The sum of five numbers is 655.
The average of the first two numbers is 77.
The third number is 128.
Formula used:
Average = (Sum of quantities) / (Number of quantities)
Calculation:
Sum of the first two numbers = 77 × 2 = 154
Sum of the five numbers = 655
Sum of the first three numbers = 154 + 128 = 282
Sum of the remaining two numbers = 655 - 282 = 373
Average of the remaining two numbers = 373 / 2
⇒ Average of the remaining two numbers = 186.5
∴ The correct answer is option (3).
