          D.  Assertion-Reason Based Questions
          Directions for Questions 1 to 2: In each of the questions given below, there are two statements
          marked as Assertion (A) and Reason (R). Mark your answer as per the codes provided below:
             (a)  Both A and R are true and R is the correct explanation of A.
             (b)  Both A and R are true but R is not the correct explanation of A.

             (c)  A is true but R is false.                 (d) A is false but R is true.

                  Reason (R)    :  LCM × (Product of two integers) = HCF

           Q. 2.  Assertion (A) :  LCM of 24 and 36 is 12.
