Answer 2

Problem Analysis

We are given that Sasha has 8 times more stamps than Andrei, and if Sasha gives Andrei 16 stamps, Sasha will have 4 times more stamps than Andrei. We need to find out how many stamps each boy has.

Solution

Let's assume that Andrei has x stamps. According to the problem, Sasha has 8 times more stamps than Andrei, so Sasha has 8x stamps.

If Sasha gives Andrei 16 stamps, Sasha will have 4 times more stamps than Andrei. This can be expressed as the equation:

8x - 16 = 4(x + 16)

Now, let's solve this equation to find the values of x and 8x.

Calculation

Expanding the equation:

8x - 16 = 4x + 64

Simplifying the equation:

8x - 4x = 64 + 16

4x = 80

Dividing both sides by 4:

x = 20

So, Andrei has 20 stamps and Sasha has 8 times more stamps, which is:

8 * 20 = 160

Therefore, Andrei has 20 stamps and Sasha has 160 stamps.

Answer

Andrei has 20 stamps and Sasha has 160 stamps.
