Question: A girl counted in the following way on the fingers of her left hand : She started by calling the thumb 1, the index finger 2, middle finger 3, ring finger 4, little finger 5 and then reversed direction calling the ring finger 6, middle finger 7 and so on.

[A].Thumb
Index finger
Middle finger
Ring finger
[A].
[B].
[C].
[D].
Answer: Option B
Explanation:
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 x 8 + 2, so 1993 shall correspond to the thumb and 1994 to the index finger.
