The sum of two numbers is 72 and one of them is twice the other. The smaller number is:
Answer: B
Let the smaller be \(x\), so the larger is \(2x\) and \(x + 2x = 72\). Then \(3x = 72\) and \(x = 24\), with the larger being 48. Check: \(24 + 48 = 72\). Answering 48 means giving the larger number rather than the smaller one asked for.
