Answer:

97 points

Step-by-step explanation:

Given,

His scores, in first test = 90 points,

In second test = 82 points,

In third test = 95 points,

In fourth test = 86 points,

Let he scores x points on the fifth test,

Thus, the total sum of the scores in five tests = 90 + 82 + 95 + 86 + x

= 353 + x

Also, The Average scores in these five test = 90

We know that,

\text{Average score}=\frac{\text{Total sum of the scores}}{\text{Total number of tests}}

Here, total number of tests = 5,

90=\frac{353+x}{5}

450=353+x\implies x = 450-353=97

Hence, the lowest score he can get on the fifth test and still finish with an average score of 90 points is 97 points.
