An ant stands on a circular track. It starts moving from a small point A on the circumference on the circle. It then moves 4 feet eastwards. Then it moves 160 degree right. Then again it moves 4 feet East and again rightwards by 160 degree . After how many movements will it come back to point A, from where it started moving.
