Question

В ДВУХ РУНДУКАХ НА КОРМЕ ЯХТЫ НАДЕЖДА ЛЕЖАТ 6 ГЕОГРАФИЧЕСКИХ карт. ЗА КАРТЫ ИЗ ОДНОГО РУНДУКА ЗАПЛАЧЕНО120 РУБЛЕЙ! А ЗА КАРТЫ ИЗ ДРУГОГО РУНДУКА 240 РУБЛЕЙ. СКОЛЬКО ГЕОГРАФИЧЕСКИХ КАРТ ЛЕЖИТ В КАЖДОМ РУНДУКЕ , ЕСЛИ ВСЕ ОНИ ИМЕЮТ ОДИНАКОВУЮ ЦЕНУ???

Answer 1

1)240+120=360руб-стоят 6 карт вместе. 
2)360:6=60руб-стоит одна карта. 
3)120:60=2 карты-лежат в 1-ом рундуке. 
4)240:6=4 карты-лежат во 20-ом рундуке

Answer 2

Solving the Problem of Geographical Maps in Two Trunks

To solve this problem, we can use a system of equations to represent the given information and find the number of geographical maps in each trunk.

Let's denote: - x as the number of geographical maps in the first trunk - y as the number of geographical maps in the second trunk

According to the given information: 1. The total cost for the maps in the first trunk is 120 rubles. 2. The total cost for the maps in the second trunk is 240 rubles. 3. The cost of each map is the same for both trunks.

We can set up the following equations based on the given information: 1. x maps in the first trunk: x * cost_per_map = 120 rubles 2. y maps in the second trunk: y * cost_per_map = 240 rubles

Since the cost per map is the same in both trunks, we can set up the equation: - x * cost_per_map = y * cost_per_map

Now, let's solve for the number of maps in each trunk.

Solving for the Number of Maps in Each Trunk

We can solve the system of equations to find the values of x and y.

From the given information, we know that the cost per map is the same for both trunks. Therefore, the number of maps in the second trunk is twice the number of maps in the first trunk.

Let's solve for the number of maps in each trunk: - x * cost_per_map = 120 rubles - y * cost_per_map = 240 rubles - Since y = 2x (the number of maps in the second trunk is twice the number in the first trunk), we can substitute y = 2x into the second equation: - 2x * cost_per_map = 240 rubles - cost_per_map = 240 / 2x - cost_per_map = 120 / x

By solving the equation 120 / x = 240 / 2x, we find: - x = 4 - y = 8

Conclusion

Therefore, there are 4 geographical maps in the first trunk and 8 geographical maps in the second trunk.
