Hi All,

We're told that N denotes a decimal. We're asked if N > 0.9 This is a YES/NO question. To answer this question, we need to use 'rounding' rules.

When a digit is 5-9, we round up. For example, 1.7 rounded to the nearest integer would be 2.

When a digit is 0-4, we round down. For example, 1.2 rounded to the nearest integer would be 1.

(1) When N is rounded to the nearest INTEGER, the result is 1.

With this Fact, we have a range of possible values for N:

0.5 <= N < 1.5

IF....

N = .85 then the answer to the question is NO

N = .91 then the answer to the question is YES

Fact 1 is INSUFFICIENT

2) When nN is rounded to the nearest TENTH, the result is 0.9

With this Fact, we have a range of possible values for N:

0.85 <= N < 0.95

IF....

N = .85 then the answer to the question is NO

N = .91 then the answer to the question is YES

Fact 2 is INSUFFICIENT

Combined, we already have 2 values that 'fit' both Facts (.85 gives us a 'NO' answer; .91 gives us a 'YES' answer).

Combined, INSUFFICIENT

Final Answer:
