Answer:
100
Step-by-step explanation:
8 yr old students = 48
Students above 8 yrs
= 2/3 of 48
= 2/3 × 48
= 32
Let the total number of students in the school be "x"
8 yr old and above students
= 32 + 48
= 80
= (100% - 20%) of total students
20% students are below 8yrs old so rest of the 80% are 8yrs old and above
= 80% of total students
= 80% of x
From above,
80% of x = 80
80/100 × x = 80
8x/10 = 80
x = 80 × 10/8
x = 100
