Given: x is an integer Target question: What is the value of x? Statement 1: 14 < 2x < 18 Divide all sides of the inequality by 2 to get:
7 < x < 9Since we're told x is an INTEGER,
x must equal 8Since we can answer the
target question with certainty, statement 1 is SUFFICIENT
Statement 2: 5 < x < 10Since we're told x is an INTEGER,
x can equal 6, 7, 8 or 9Since we can’t answer the
target question with certainty, statement 2 is NOT SUFFICIENT
Answer: A
Cheers,
Brent
