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 ?

A. Thumb
B. Index finger
C. Middle finger
D. Ring finger

• 
  Ans: B.
  Clearly, while counting the numbers associated to the thumb will be 1,9,17,25,.........
  i.e., numbers of the form (8n + 1 ).
  where n=1,2,3...
  Since 1994 = 249 × 8 + 2, so 1993 shall correspond to the thumb and 1994 to the index finger.

  1994/5 = remaining 4

  so 1994/4 gives remainder 0... ans is middle finger

• Ans: index finger
  explanation: 1994/10 gives 4 remainder, then now count from small finger bcoz after 1-5 from thumb to small then 6-10 from small to thumb therefore we need to count from small finger.. Then answr index finger
