Can you explain your solution? Thank you.
@YH Tan, at 1st average score was 70. After 1 man joined in, average become 66. That mean everyone is lossing 4 point.
The other hand, new man join in with score 50, he gain 16 points (50+16=66), meaning he gain the point from all the guys before join, each gave 4 points, so 4 men gave 16 points, so we knew this at 1st is 4 men. In the end is 5 men
