The product of two numbers is (15120) and their HCF is (36). If one number is (216), what is the other number?
Answer and explanation
Correct answer: (70)
Step 1: Since the product is directly given, the other number is (15120\div 216). Step 2: (15120\div 216=70). On checking, the HCF of (216) and (70) is (2), so the given HCF (36) is inconsistent. Step 3: In exams, if conditions conflict, first compute the basic quotient and then verify the condition.
