10th Class Mathematics Real Numbers Question Bank Assertion And Reason (MCQs) - Real Numbers

  • question_answer
    Assertion (A): If LCM = 350, product of two numbers is \[25\times 70,\] then their HCF = 5.
    Reason (R): LCM x Product of numbers = HCF.

    A) Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A)

    B) Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A)

    C) Assertion (A) is true but reason (R) is false

    D) Assertion (A) is false but reason (R) is true

    Correct Answer: C

    Solution :

    Sol. [c] \[\text{LCM}\times \text{HCF}=\]Product of numbers   
    \[\Rightarrow \,\,\,350\times HCF=25\times 70\Rightarrow HCF=\frac{25\times 70}{350}=5\]               
    Assertion: True; Reason: False.
