The average of seven consecutive positive integers is 26. The smallest of these integers is :
-
- 21
- 23
- 25
- 26
- 21
Correct Option: B
As we know that ,
Sum of integers = average × Total number of integers
y + y + 1 + y + 2 + y + 3 + y + 4 + y + 5 + y + 6 = 26 × 7
⇒ 7y + 21 = 182
⇒ 7y = 182 – 21 = 161
| ⇒ y = | = 23 | |
| 7 |
Second method to find the required answer ,
Fourth number = 26
∴ First number = 23
