Detailed Solution
Download Solution PDFGiven:
Sum of five numbers = 655
Average of first two numbers = 78
Third number = 110
Formula used:
Sum = Average × Total numbers
Remaining two numbers = Total sum - (Sum of first two numbers + Third number)
Calculation:
Sum of first two numbers = 78 × 2 = 156
Sum of first three numbers = 156 + 110 = 266
Sum of remaining two numbers = 655 - 266 = 389
Average of remaining two numbers = 389 / 2
⇒ Average = 194.5
∴ The correct answer is option (1).
