###Human: A chocolate box contains 200 bars. Thomas and his 4 friends take 1/4 of the bars and decide to divide them equally between them. One of Thomas's friends doesn't like chocolate bars very much and returns 5 of his bars to the box. Later, his sister Piper comes home and takes 5 fewer bars than those taken in total by Thomas and his friends so she can also share with her friends. What's the total number of bars left in the box?, ### Assistant: Thomas and his friends took 1/4*200 = 50 bars.
The total number of bars left in the box was 200-50 = 150 bars.
Since there are five of them sharing, each of them got 50/5 = 10 bars.
After a friend returned 5 bars, there were 150 + 5 = 155 bars in the box.
Piper took five fewer bars, that is 50 - 5 = 45 bars.
The total remaining bars left in the box is 155 - 45 = 110 bars. 
 So the answer is :  110
