Mr. Chan bought some pencils for a group of students. If he gives them 2 pencils each, he will have 10 pencils left. If he gives them 3 pencils each, he will have none left.
How many students are in the group?
Answer (3)
He has 10 students. If he give 2 each, that's 20 pencils, but he has 10 left. If he give 3 each, that's 30. No pencils left over.
30 student, if I'm not wrong.
Mr. Chan has 10 students in the group. When he distributes 2 pencils to each, he has 10 left, and when he gives 3 pencils, he has none left. Both calculations confirm the number of students is correct.
