Dennis score 7.5mark in a test and it is equivalent to 93.75%.what is the total marks for the test?

.9375x = 7.5

93.75x=7.5

750/93.75=8

To find the total marks for the test, we need to set up a proportion based on the given information.

We know that Dennis scored 7.5 out of a total of x marks. And this score of 7.5 is equivalent to 93.75% of the total marks.

Let's set up the proportion:
7.5 / x = 93.75 / 100

To solve this proportion, we can cross-multiply and solve for x:
(7.5 * 100) = (93.75 * x)

750 = 93.75x

To find the value of x, divide both sides of the equation by 93.75:
x = 750 / 93.75

Now, calculate the value of x:
x = 8

Therefore, the total marks for the test is 8.
