Step-by-Step Solution
The complete worked solution.
Every step explained - no skipped algebra.
15 is written as 3n₃n₃n and 25 as 5n₅n₅n.That means when n=5n = 5n=5, we get the pair 15:25.
Now if 24 is 3n₃n₃n, then n=8n = 8n=8.So the matching number will be 5n=405n = 405n=40.
Final Answer: Option A - 40
