Verified Answer
A girl counted in the following way on the fingers of her left hand : ...
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.

A girl counted in the following way on the fingers of her left hand : ...
**Solution:**
To find out on which finger the girl ended counting, we need to analyze the pattern of counting.
Let's break down the counting process into two parts:
**Part 1: Forward Counting**
- The girl starts by calling the thumb 1, the index finger 2, the middle finger 3, the ring finger 4, and the little finger 5.
- After reaching the little finger, she reverses the direction.
**Part 2: Reverse Counting**
- The girl starts by calling the ring finger 6, the middle finger 7, and so on.
Now, let's observe the pattern and see if we can find any clues.
**Forward Counting:**
- The girl starts with the thumb as 1.
- The index finger is the second finger, so it is called 2.
- The middle finger is the third finger, so it is called 3.
- The ring finger is the fourth finger, so it is called 4.
- The little finger is the fifth finger, so it is called 5.
**Reverse Counting:**
- The ring finger is the sixth finger, so it is called 6.
- The middle finger is the seventh finger, so it is called 7.
- The index finger is the eighth finger, so it is called 8.
From the pattern, we can observe that the girl counts in cycles of 8 fingers.
If we divide 1994 by 8, we get a quotient of 249 and a remainder of 2.
Since the remainder is 2, it means the girl would have ended counting on the **index finger** (which is the second finger) after completing 249 cycles of 8 fingers.
Therefore, the correct answer is option **b) Index finger**.
