1/6 of the class students are above average, 1/4 are average and rest are below average. If there are 48 students in all, how many students are below average in the class?
Solution:
Given there are 48 students
Those who are above average = 1/6(total students) = 1/6(48) = 8
Those who are average = 1/4(total students) = 1/4(48) = 12
Therefore, those who are below average = total - above average -average
= 48 - 8 - 12
= 28
Hence, there are 28 below average students
✦ Try This: 1/6 of the class students are above average, 1/4 are average and rest are below average. If there are 36 students in all, how many students are below average in the class?
Given there are 36 students
Those who are above average = 1/6(total students) = 1/6(36) = 6
Those who are average = 1/4(total students) = 1/4(36) = 9
Therefore, those who are below average = total - above average -average
= 36 - 6 - 9
= 21
Hence, there are 21 below average students
