Question

Chenyqua is taking a test. After 20 minutes, she has 35 questions left. After 40 minutes, she has 15 questions left. If Chenyqua takes the same amount of time for each question, how many questions are on the test?

Answer 1

35-15=20 20+35=55. That's the answer.

Answer 2

There were 55 questions in the test.

Explanation:

After 20 minutes, Chenyqua has 35 questions left. After 40 minutes, she has 15 questions left.

We can see that in 20 minutes (40-20) she has done 20 questions (35-15)

Means she takes 1 minute for 1 question.

Lets suppose the initial questions in the test was = x

So, we can say that
`x-20=35`

`x=35+20=55`

In the second phase, we can again see,
`x-40=15`

`x=15+40=55`

Therefore, there were 55 questions in the test.
