Answer 1

He answers 36 correct

Answer 2

Correct answer is 36

Explanation:

Given that Jeremiah answers 90% of the questions on his test correctly.

This means that out of 100 questions he answered 90 questions correctly.

Total number of questions in the test = 40

When for 100 questions correct answer is 90,

This is a question on direct variation.

Hence answer is
`(40(90))/(100) =36`
