Correct Answer - Option 2 : 23
Given:
The average of 6 consecutive odd numbers is 28.
Formula used:
Average = Sum of observation/Total number of observation
Calculation:
Let the smallest number is x,
So, rest of the number will be (x + 2), (x + 4), (x + 6), (x + 8), (x + 10)
⇒ x + x + 2 + x + 4 + x + 6 + x + 8 + x + 10 = 28 × 6
⇒ 6x + 30 = 168
⇒ 6x = 138
⇒ x = 23
∴ The smallest number is 23.
