Question

1/6 of the class students are above average, ¼ are average and rest

are below average. If there are 48 students in all, how many students are below

average in the class?​

Answer 1

Answer:

28

Step-by-step explanation:

1/6 = A.A

1/4 = A

x   = B.A

total no . of students in the class = 48

no . of students who are A.A = 1/6×48=8

no . of students who are A    = 1/4×48=12

no . of students who are B.A = 48-8+12=48-20=28

so basically

total no . of students who are below average =  1-1/6+1/4

                                                               = 1-5/12

                                                                = 7/12

      no . of students who are below average = 7/12×48

                                                                ⇒ 28 .
