Sangho uploaded a video to a website where viewers can vote that they like or dislike a video. Each video begins with a score of $0$, and the score increases by $1$ for each like vote and decreases by $1$ for each dislike vote. At one point Sangho saw that his video had a score of $100$, and that $60\%$ of the votes cast on his video were like votes. How many votes had been cast on Sangho's video at that point?
