Question

in a class 72 students passed and rest failed.if 60% failed find the no.of students in class​

Answer 1

Step-by-step explanation:

so, the total no. of students are 180.

Answer 2

Let the total no. of students in the class be 'x'

72 students passed

(x-72) students failed

but we know that

60% failed

hence,

$\frac{60x}{100}$ = x-72

6x = 10x-720

4x = 720

x = 180

that is, the total no. of students in the class is 180
