The average of 5 numbers is 34. If there are 28, 30, 32, then find the average of rest of them?
- 30
- 40
- 50
- None of these
Explanation
We are told:
Average of 5 numbers = 34
Total sum of 5 numbers = 34 × 5 = 170
Given 3 numbers: 28, 30, 32
Sum of these = 28 + 30 + 32 = 90
Remaining sum = 170 - 90 = 80
Remaining numbers = 2
Average of remaining = 80 ÷ 2 = 40
