Soal SMP · Soal cerita · Kesulitan 3/5
A group of students is divided into teams. If each team has 6 students, there will be 3 students left. If each team has 7 students, there will be 4 students left. What is the smallest possible number of students in the group?
- A.39 students
- B.45 students
- C.51 students
- D.57 students
Kunci jawaban & pembahasan
Jawaban: 39 students
Let students = N. N = 6a + 3 and N = 7b + 4. Testing values: N = 39 gives 39 ÷ 6 = 6 remainder 3, and 39 ÷ 7 = 5 remainder 4. So the smallest is 39.
