Answer 2

Calculating the Number of Pages Occupied by German Stamps

To find out how many pages were occupied by the German stamps, we can use the given information and some basic algebra.

Let's denote: - B as the number of Bulgarian stamps - N as the number of German stamps - P as the total number of pages

Given: - The boy had 24 Bulgarian and 40 German stamps. - The stamps were placed in the album, with an equal number on each page. - The German stamps occupied 2 more pages than the Bulgarian stamps.

We can set up the following equations: 1. B + N = total number of stamps 2. B = N - 2 3. B * P_per_B + N * P_per_N = total number of stamps (where P_per_B and P_per_N are the number of pages occupied by Bulgarian and German stamps, respectively)

We can solve these equations to find the number of pages occupied by the German stamps.

Solution

Using the given information, we can solve for the number of pages occupied by the German stamps.

From the first equation, we have: - B + N = 24 + 40 - B + N = 64

From the second equation, we have: - B = N - 2

Substituting the value of B from the second equation into the first equation: - (N - 2) + N = 64 - 2N - 2 = 64 - 2N = 66 - N = 33

So, the number of German stamps (N) is 33.

Now, we can find the number of pages occupied by the German stamps: - N * P_per_N = 40 (since the total number of German stamps is 40)

Therefore, the German stamps occupied 40 pages.

Final Answer

The German stamps were occupied on 40 pages in the album.
