Statement 1: c < a + b – 1 Take: a + b + c < 0 Subtract a and subtract b from both sides to get: c < -a - b Now add this inequality to the statement 1 inequality: c < a + b – 1 We get: 2x < -1 Divide both sides by 2 to get: c < -1/2 If c < -1/2, then c is definitely less than 1 So, the answer to the target question is YES, x IS less than 1 Since we can answer the target question with certainty, statement 1 is SUFFICIENT
Statement 2: a + b − 1 > 0 Take: a + b − 1 > 0 Rewrite as: 0 < a + b - 1 Add c to both sides to get: c < a + b + c - 1 Add 1 to both sides to get: c + 1 < a + b + c We already know that a + b + c < 0 So, we can add this info to our inequality to get: c + 1 < a + b + c < 0 This tells us that c + 1 < 0 Subtract 1 from both sides to get: c < -1 If c < -1, then c is definitely less than 1 So, the answer to the target question is YES, x IS less than 1 Since we can answer the target question with certainty, statement 2 is SUFFICIENT
