A woman bought 200 oranges and sold 40% of them on the market day how many oranges would she have left?
The number of oranges sold is 40% of 200 oranges which is (40/100)*200 = <<40/100*200=80>>80 oranges
If she sold 80 oranges out of 200, she would have 200-80 = <<200-80=120>>120 oranges left. Answer: \boxed{120}.
