Answer:

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

Step-by-step 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

\frac{80}{100}x=20\\0.8x=20

Dividing both sides by 0.8

\frac{0.8x}{0.8}=\frac{20}{0.8}\\x=25

Hence,

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