In a certain school, 20% of students are below 8 years of age. The number of students above 8 years of age is 2/3 of the number of students of 8 years age which is 48. What is the total number of students in the school?
A72
B80
C100
D120
✓ Correct Answer: C — 100
Students age 8 = 48. Students > 8 = 2/3 * 48 = 32. Total >= 8 = 80. These 80 students represent 80% of the school. Total = 100.
