Amar and Balu start running from the same point in a circular track with speeds 8 kmph and 10 kmph respectively. Find the number of distinct points at which Amar and Balu meet on the track .

The number of distinct points if they are running in the same direction is x-y if the speeds are in the ratio x:y respectively where x:y ratio is in the lowest possible form. Hence, the 8:10 would be expressed as 4:5 and the number of distinct points would be 5-4= 1 point.
