Answer:

The student had a total of 25 questions on his test.

Explanation:

Given that:

Number of questions answered correctly in the test = 20

Percentage scored in the test = 80%

Let,

x be the total number of questions on test.

We know that 80% of the test is 20 questions, therefore,

80% of x = 20

$(80)/(100)x=20\\0.8x=20$

Dividing both sides by 0.8

$(0.8x)/(0.8)=(20)/(0.8)\\x=25$

Hence,

The student had a total of 25 questions on his test.
