A group of people sit thier driving test and 24 people passed.80 percent of the people passed the driving theory test.how many people sat the test altogether

Answer 1

30 people took the exam

Explanation:

24 people passed.

They represent 80% of the total.

Lets say the total is X.

We can write (0.80)X = 24 [80% of the total passed, which was equal to 24]

(0.80)X = 24

X = (24)/(0.80)

X = 30 people took the exam
