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. She counted upto 1994. She ended counting on which finger ?
Answer: Option
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.

Your counting pattern is very incomprehensible, after 9, the next figure on the thumb is 14.
How did you get 17? Please explain me.

How the sequence be 1, 9, 17... Can you please elaborate. First two digits 1 and 9 are correct and later on how 17 will come?

@Arohi,
You reverse the direction when counting, 10 lands on the index finger and 15 lands on the middle finger.

Total count for 8 fingers.
Therefore, 1994 divided by 8 gives=2 as remainder.
Hence 2 finger i.e. index finger.
Therefore, 1994 divided by 8 gives=2 as remainder.
Hence 2 finger i.e. index finger.

10 is not the index finger because we start our counting from the thumb.
So the answer is the ring finger.
So the answer is the ring finger.

The thumb finger gets the value 1, 9, 17, ... etc. So the difference between each is 8.

Please explain where numbers of the form 8n + 1 come from. I don't understand.

Ring finger is correct because we get 4 in unit's place only on it.

1994 is divisible by only 2. And hence the index finger.
