Question

in a class 72 students passed and the rest failed . if 60% of the students failed find the number of students in a class

Answer 1

Answer:

Here is ur answer

Step-by-step explanation:

Given ; 72 students passed and 60% of students failed

100%-60% = 40%(No.of students passed)

72 passed = 40% Passed

100%-60%=72

  If you take 40 percent of a number and get 72, then what is that number?

In other words, you know that 40 percent of a number is 72 and you want to know what that initial number is.

To solve this problem you multiply 72 by 100 and then divide the total by 40 as follows:

(72 x 100) / 40

When we put that into our calculator, we get the following answer:

180

180-60%=72

60%=108

Hope this answer will help u a lot
