(1) When k is rounded to the nearest tenth, the result is 0.5.
(2) When k is rounded to the nearest integer, the result is 0
OA IS B
(1) Both 0.49 and 0.51 rounded to the nearest tenth, result in 0.5. Hence k could be less or more than 0.5. Insufficient
(2) A decimal equal to or more than 0.5, rounded to the nearest integer, results in 1. But, a decimal less than 0.5, rounded to the nearest integer, results in 0. Therefore, the decimal k [spoiler]
must be less than 0.5. Sufficient
