Solve for the missing multiplier: 75% of 480 equals (?) × 15. Find (?).

Difficulty: Easy

Correct Answer: None of these

Explanation:


Introduction / Context:
We equate a known percent of a number to a simple product and solve for the unknown multiplicative factor. This is an algebraic one-step solve after computing the percent value.


Given Data / Assumptions:

  • LHS: 75% of 480.
  • RHS: (?) × 15.


Concept / Approach:
Compute the left-hand side first. Then divide by 15 to isolate (?). Verify if the result is present among the options.


Step-by-Step Solution:

75% of 480 = 0.75 * 480 = 360.So (?) × 15 = 360 ⇒ (?) = 360 / 15 = 24.


Verification / Alternative check:
Check: 24 × 15 = 360, matching 75% of 480. Therefore, the correct value is 24.


Why Other Options Are Wrong:

  • 32 and 18 produce 480 and 270, not 360.
  • 360 is the LHS value, not the multiplier (?); it would correspond to 360 × 15, which is incorrect.
  • The exact correct value 24 is not listed among the main options, so “None of these” is appropriate.


Common Pitfalls:
Stopping after computing 360 and selecting it as the answer. The question asks for the multiplier (?), not the percent result.


Final Answer:
None of these
