Students participating in a test must obtain at least a certain score in the first round to qualify for the next round. There were 130 students in the first round and the table shows the number of students for each score. 70% of the students did not qualify for the next round. From the table, what was the lowest score of a student who qualified for the next round?

Score	Number of students
0	15
1	20
2	27
3	29
4	23
5 or more	16

Score	Number of students	Status
0	15	70% of students did not qualify
1	20
2	27
3	29
4	23	30% of students qualified
5 or more	16

Percent of students who qualified for the next round
= 100% - 70%
= 30%

Number of students who qualified for the next round
= 30% of students
= ³⁰₁₀₀ x 130 
= 39

Number of students who score 5 or more = 16
Number of students who score 4 or more = 16 + 23 = 39

Lowest score of a student who qualified for the next round = 4

Answer(s): 4
