Class 8.A

Three-quarters of class 8A went skiing. Of those who remained at home, one-third were ill, and the remaining six were on math Olympic. How many students have class 8A?

Correct answer:

x =  36

Step-by-step explanation:

3/4 x + (1-3/4) x/3 + 6 = x

3/4·x + (1-3/4)·x/3 + 6 = x

2x = 72

x = 72/2 = 36

x = 36
