Answer 1

ANSWER

72% of the total number of students went for a picnic.

Remaining 28% of the students did not go for the picnic.

The number of students that did not go for the picnic is 569.

Let the total number of students in the class be x.

Therefore , 28% of the total number of students is 569.

Students who do not go for the picnic = 0.28x

569 = 0.28x

x ≈ 2032

Number of students in the class is 2032

Step-by-step explanation:

Answer 2

actually first we can take it as the total No.of students=100 percentages
In that, 72% of the total number of students
so, 100 percent, -72 percent= 28 percent : Who didn't go to the picnic: 1st step
28 percent* total students= 560
28/100 * x =560
when 28/100 percent moves to that 560 side it becomes as 560*100/28
So that x= 560*100/28
so 560 and 28 comes in 28 table so we can cross them both
so, 560/28=20
20*100
2000 is the total number of students
