Tables

The ninth-grade students are on a day trip. In the morning, the trippers had refreshments at a candy store. They sat down at tables in groups of three and took all the seats. At lunch, they sat down at a table in groups of four and again took all the seats. And there were two fewer tables there than in the candy store. How many students are on the trip and what is the number of tables?

Correct answer:

n =  24
s1 =  8
s2 =  6

Step-by-step explanation:

3 ...  prime number 4=22 LCM(3,4)=223=12  k=LCM(3,4)=12  n/4+2=n/3  n=24  n=124=24  n=24
s1=n/3=24/3=8
s2=n/4=24/4=6
