Problem Analysis

The operator typed 28% of the manuscript on the first day and 20% on the second day. After that, the operator had 39 pages left to type. We need to determine the total number of pages in the manuscript.

Solution

Let's assume the total number of pages in the manuscript is x.

On the first day, the operator typed 28% of the manuscript, which is equal to 0.28x pages. On the second day, the operator typed 20% of the manuscript, which is equal to 0.20x pages.

After the two days, the operator had 39 pages left to type. So, the equation becomes:

x - (0.28x + 0.20x) = 39

Simplifying the equation:

x - 0.48x = 39

0.52x = 39

Dividing both sides by 0.52:

x = 39 / 0.52

Calculating the value of x:

x ≈ 75

Therefore, the total number of pages in the manuscript is approximately 75.

Answer

The total number of pages in the manuscript is approximately 75.
