Below are sample questions representative of the exercises included on this worksheet and related 4.108 Use Logical Reasoning to Find Unknown Numbers skill assessments:

Problem 1Difficulty: Mastery
A number n is divisible by 9 and is 2 less than a multiple of 8. Also, 150 < n < 200. What is n?
Solution & Explanation:List multiples of 9 between 150 and 200: 162, 171, 180, 189, 198. Check which is 2 less than a multiple of 8: 198 + 2=200, and 200 is divisible by 8. So n=198.
Problem 2Difficulty: Mastery
Which number n satisfies: n is a multiple of 11, n is a multiple of 6, n is between 100 and 150, and n has a digit sum of 6?
A144
B132
C110
D121
Solution & Explanation:A number that is a multiple of both 11 and 6 must be a multiple of 66. Between 100 and 150, the only multiple of 66 is 132. Its digit sum is 1 + 3 + 2=6, so the correct choice is B.
Problem 3Difficulty: Mastery
Three numbers are factors of 180 and add to 31. Two of the numbers are consecutive even numbers. What is the greatest number?
Solution & Explanation:Consecutive even numbers differ by 2. The factor pair 10 and 12 are consecutive even factors of 180. Their sum is 22, so the third number must be 31-22=9, which is also a factor of 180. The greatest of 9, 10, and 12 is 12.
