d can be anything between 0.45 to 0.54. So, the answer cannot be unique yes or no. Insufficient.
Statement 2: When d is rounded to the nearest integer, the result is 1.
d must be 1 the number between 0.5 to 0.9; so in any case, d ≥ 0.5. Sufficient.
The correct answer: B
Hope this helps!

We are given that d is a decimal, and we need to determine whether d is greater than or equal to 0.5.vaibhav101 wrote:If d denotes a decimal, is d greater than or equal to 0.5?
(1) When d is rounded to the nearest tenth, the result is 0.5.
(2) When d is rounded to the nearest integer, the result is 1.
Statement One Alone:
When d is rounded to the nearest tenth, the result is 0.5.
Using the information in statement one, we can get a multitude of values for d.
For example, d can be 0.51, and 0.51 is greater than or equal to 0.5.
In another case, d can be 0.49, but 0.49 is not greater than or equal to 0.5.
Statement one is not sufficient to answer the question. We can eliminate answer choices A and D.
Statement Two Alone:
When d is rounded to the nearest integer, the result is 1.
In order for d to be rounded to 1 (when rounded to the nearest integer), the value of d must be at least 0.5. Statement two is sufficient to answer the question.
