[New India Insurance (AAO), 2011]

    • Explanation

    Here, HCF of two 4-digits numbers=103

    ∴ Let the numbers be 103a and 103b

    And LCM of 103a and 103b=19261

    or  103(a×b)=19261

    ⇒ a×b=187

    or a=11 or 17 and b=11 or 17

    ∴ Numbers =103×11=1133

    = 103×17=1751

    ∴ Sum of these two numbers =2884.

    Hence, Option A is correct.
