Let a, b, c, d be four single digit positive integers such that a + b = 11, b + c = 9. If ab > bc > cd, then a = ?
Question
Solution 1
Given that a + b = 11 and b + c = 9, we can infer that a, b, c are all single digit positive integers.
Step 1: Since a + b = 11 and both a and b are single digit integers, the possible pairs (a, b) are (2, 9), (3, 8), (4, 7), (5, 6).
Step 2: Similarly, since b + c = 9, the possible pairs (b, c) Knowee AI is a powerful AI-powered study tool designed to help you to solve study problem.
