8.
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.

I divided 1990 by 5(no 5 stops on little finger and no 10 falls on thumb)since little finger not given in options we divide by 5..so we get 1990 on little finger.
Now count reverse 1999 wil come on index.
Now count reverse 1999 wil come on index.

Here Arithmetic progression rule followed :
a+(n-1)d nd aftr dat 2a+(n-1)d for calculating sum of and the result will be proceeding of 1 so we extend 1 nd we finally get index which is after thumb.

1994 may be divide purely by only 2 then at two number position which finger is, the finger is Index finger at second position, which comes after thumb, so answer is Index finger.

Index finger is absolutely right answer. i.e.,(8n+1) is the thumb in this case 1992 is multiplication of 249x8. So (8x249+1)=1993 is thumb then next finger is index finger.

I divided 1994 by 4 (except first time we are counting 4 nos for one side) so remainder is 2 we started with thumb 1, the index finger 2, so the answer is index finger.

5,10,15.......comes on the little finger.
I.e 5n is on the little finger.
Again 5*399 = 1995 is on the little finger. So obviously 1994 will come on the ring finger.
I.e 5n is on the little finger.
Again 5*399 = 1995 is on the little finger. So obviously 1994 will come on the ring finger.

As we found the form of the sequence is 8n+1.
Then divide 1994 by 8. Resultant is 249 and remainder is 2. So now (n=249)8+2.
2 means 2nd finger 4 index finger.
Then divide 1994 by 8. Resultant is 249 and remainder is 2. So now (n=249)8+2.
2 means 2nd finger 4 index finger.

I agree. It should be middle finger. 1992 is thumb then plus 2 remainder. Therefore, 1992 + 1 = 1993 (index) then 1993 + 1 = 1994 which points to middle finger.

249*8=1992 it appears on thumb and 1993 comes on index and 1994 on middle finger.
So answer in middle finger if apply 8n+2=(8*249+2)=1994.
So answer in middle finger if apply 8n+2=(8*249+2)=1994.

Series for thumb 1, 9, 17, 25, 33.
i.e general term is 8n+1.
1994 divided by 8 gives remainder 2.
So the answer should be INDEX FINGER.
