Basic Mathematics QUESTION #7988
Question 1
The equation \(x + a = b\) has a solution in the set of natural numbers if:
  • a < b✔️
  • a > b
  • a = b
  • None of these
Correct Answer Explanation
\(x + a = b \Rightarrow x = b - a\). For \(x\) to be a natural number (positive integer), we need \(b - a \geq 1\), i.e., \(b > a\), or equivalently \(a < b\).
