Question

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

Answer 1

Answer:

There are 80 marks in total.

Step-by-step explanation:

Let the number of total marks be $x$.

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

$\displaystyle \frac{68}{x} = 85\%$.

However,

$\displaystyle 85\% = \frac{85}{100}$.

Equating the two:

$\displaystyle \frac{68}{x} = \frac{85}{100}$.

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

$85x = 68\times 100$.

$\displaystyle x = \frac{68\times 100}{85} = 80$.

In other words, there are 80 marks in total.
