The sum of n consecutive positive integers is 45. What is the value of n?
(1) n is odd
(2) n >= 9
(1) n is odd
(2) n >= 9
(1) The sum of consecutive integers will always be divisible by the number of integers only if the number of integers is odd.
n can be 3/5/9. Insufficient.
n can be 3/5/9. Insufficient.
(2) We can have n=9/10 but since we are talking of +ve int only. Hence it would be 9. This is sufficient.
Ans : B
Thank you for the good post.
ReplyDeleteThere is a meaning that in the nearest future we will not need to make any calculations on our own because of developed cloud computing. I'd like to say that some fields of business are operated by it. For instance, m&a data room services.
