    Answer:

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

    Step-by-step 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

    \frac{150}{100}x=54

    1.5x=54

    Dividing both sides by 1.5

    \frac{1.5x}{1.5}=\frac{54}{1.5}\\x=36

    Hence,

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