Question

In a mathematics​ class 54, students received an A on the third​ test, which is ​150% of the students who received an A on the second test. How many students received an A on the second​ test?

10,1 #16

Answer 1

Number of students who received A grade on the second test = 36

Explanation:

Given that:

Number of students who received A grade on third test = 54

This is 150% of the students who received A on the second test.

Let,

x be the number of students who received A on the second test.

150% of x = 54

`(150)/(100)x=54`

1.5x=54

Dividing both sides by 1.5

`(1.5x)/(1.5)=(54)/(1.5)\\x=36`

Hence,

Number of students who received A grade on the second test = 36
