increased by 15
past score was x
increased by 15 means he raised to 15+x
it was raised to 83%

therefor
x+15=83

first option is right (and first test was 68%)

Answer:

The correct equation is x+15=83

Option 1 is correct.

Explanation:

When Jose took the test over, he increased his score by 15% points

Let he scored in first test x%

In second test scored 83% which was 15% more than first test.

He increased his score by 15% points from first test.

Thus, Scored in second test = x + 15

We are given second test scored 83%

Therefore, x+15 must be equal to 83

Hence, The correct equation is x+15=83
