Assertion (A): The HCF of two numbers is 5 and their product is 150. Then their LCM is 40.
Reason(R): For any two positive integers a and b, HCF (a, b) × LCM (a, b) = a × b.
पर्याय
Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).
Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).
Assertions (A) is true but reason (R) is false.
Assertions (A) is false but reason (R) is true.
उत्तर
Assertions (A) is false but reason (R) is true.
Explanation:
Assertion: Given that, HCF = 5
LCM = 40
Product of numbers = 150
We know that,
HCF × LCM = Product of numbers
HCF × LCM = 5 × 40
= 200 is not equal to the product
So, Assertion is false
Reason: For any two positive integers a and b, HCF (a, b) × LCM (a, b) = a × b.
Hence, Assertion is false but reason is true.
