The quotient of ,a number and five, equals nine less than one half of the number. What is the number?

Explanation

Let the number be represented as x. The equation formed is x/5 + 9 = x/2. Simplifying further, we get x = 30. Therefore, the correct answer is 30. Option A and B are incorrect as they assume negative values for the number which don't satisfy the equation. Option C is incorrect as substituting 20 in the equation does not satisfy both sides of the equation.
