| Consider the sequential integers 27 to. 93, both included in the sequence. The arithmetic average of these numbers will be |
A) 61.5
B) 61
C) 60.6
D) 60
Correct Answer: D
Solution :
| From 27 to 93 total numbers \[=67\] |
| \[\therefore \]Sum of these numbers \[=\frac{93\times 94}{2}-\frac{26\times 27}{2}\] |
| \[=4371-351=4020\] |
| \[\therefore \]Arithmetic average of these numbers \[=\frac{4020}{67}=60\] |
