Question

A student gets 68 marks n therefore gets 85 percent total marks are?

Answer 1

There are 80 marks in total.

Explanation:

Let the number of total marks be
`x`.

The percentage score of the student can be written as the ratio

`\displaystyle (68)/(x) = 85\%`.

However,

`\displaystyle 85\% = (85)/(100)`.

Equating the two:

`\displaystyle (68)/(x) = (85)/(100)`.

Cross-multiply (that is: multiple both sides by
`100x`, the product of the two denominators) to get

`85x = 68* 100`.

`\displaystyle x = (68* 100)/(85) = 80`.

In other words, there are 80 marks in total.
