    A girl counted in the following way on the fingers of her 1 hand: She started by calling the thumb 1, the index finger middle finger 3, ring finger 4, little finger 5 and then reversed direction calling the ring finger 6, middle finger 7 and so on. She counted upto 1994. She ended counting on which finger?

    A) Thumb             

    B) Index finger

    C) Middle finger                 

    D) Ring finger

    Correct Answer: B

    Solution :

    Clearly, while counting, the numbers associated to the thumb will be 1, 9, 17, 25, ... i.e., numbers of the form \[(8n+1).\] Since, \[1994=249\times 8+2,\] so 1993 snail correspond to mi thumb and 1994 to the index finger.
