  • question_answer
    Directions: Each of these questions contains two statements: Assertion [A] and Reason [R]. Each of these questions also has four alternative choices, any one of which is the correct answer. You have to select one of the codes [a], [b], [c] and [d] given below.
    Assertion [A] We can say that \[3|93\]and 5)0 is true.
    Reason [R] A non-zero integer a is said to divide an integer b if there exists an integer c such that b = ac.

    A) A is true, R is true; R is a correct explanation for A.

    B) A is true, R is true; R is not a correct explanation for A.

    C) A is true; R is False.

    D) A is false; R is true.

    Correct Answer: A

    Solution :

    If 3|93 means 3 divides 93  
    \[\Rightarrow \,\,93=a\times 3\]                 (a is an integer)
    Similarly, if  5|0 means 5 divides 0
    \[\Rightarrow \,\,\,0=5\times b\]                (b is an integer)
    \[\therefore\]  Assertion is true Reason is true and Reason is the correct explanantion of Assertion.
