Question

Adriel answered 54 questions correctly on his multiple choice history final and earned a grade of 45%. How many total questions were on the final exam?

Answer 1

There were 120 questions on the test.

Explanation:

It is given that:

Number of questions answered = 54

Grade percent = 45%

Let,

x be the total number of questions

45% of x = 54

`(45)/(100)x=54\\0.45x = 54`

Dividing both sides by 0.45

`(0.45x)/(0.45)=(54)/(0.45)\\x=120`

Therefore,

There were 120 questions on the test.
