Sum of five numbers = 655
Average of the first two numbers = 78
Third number = 103
Formula Used:
Average = Sum of numbers / Total numbers
Calculation:
Sum of the first two numbers = Average × Total numbers
Sum of the first two numbers = 78 × 2
⇒ Sum of the first two numbers = 156
Sum of the remaining two numbers = Total sum - (Sum of the first two numbers + Third number)
Sum of the remaining two numbers = 655 - (156 + 103)
⇒ Sum of the remaining two numbers = 655 - 259
⇒ Sum of the remaining two numbers = 396
Average of the remaining two numbers = Sum of the remaining two numbers / 2
Average of the remaining two numbers = 396 / 2
⇒ Average of the remaining two numbers = 198
The average of the remaining two numbers is 198.
