Stamp collecting in primary school mathematics
CoCo Lee. Wang Lan. Zhang Cong is a stamp collector. Please do as they say. Do the math. How many stamps do the three of them have

Wang Lan: If the number of stamps in CoCo Lee is six times as much as it is now, my number of stamps will be one third as much as it is now, and the number of stamps in Zhang Cong will remain unchanged. We have 65,438+000 stamps.

Wang Min: We have 100 stamps. Zhang Cong: I have less than 30 stamps. A: The number of stamps in CoCo Lee is five times that in Wang Lan = 2/3. It is known that the ratio of stamps in CoCo Lee and Wang Lan is 2: 15, that is, the total number of stamps for two people is a multiple of 17 and more than 70, so the total number of stamps for two people is 85, that for CoCo Lee is 10 and that for Wang Lan is 75.
