10
11
45
65
Explanation:
Total pencils=605.
Let total boys are =X each student is getting pencils 20% of the total number of students
=X*20/100
=X/5 it is also equal to 605/X
or 605/X=X/5.
X^2=605*5
X=55 therefore number of pencils each student get
= 605/55
=11 pencils
Total pencils=605.
Let total boys are =X each student is getting pencils 20% of the total number of students
=X*20/100
=X/5 it is also equal to 605/X
or 605/X=X/5.
X^2=605*5
X=55 therefore number of pencils each student get
= 605/55
=11 pencils
