What is the percentage of students with less than 75 percent attendance?

Answer 1

Answer:

Total percent of the students in the school have less than 75% attendance is given by 12.5%.

Step-by-step explanation:

Let total student be x

Student having less than 75% be y

Then

Not allowed to sit from x= not allowed to sit from y

X(1/10)=y(4/5)

Y/x. =1/8 =12.5%
