Answer:

The total number of questions are 40

Explanation:

let the total number of questions be "x".

percent of questions answered correctly are 80.

In fractions 80% is
(4)/(5)

The total number of correctly answered questions are 32.

the equation is,


((4)/(5))(x) = 32

thus , x =
((5)(32))/(4)

x= 40
