Question

В двух амбарах было 3090 кг зерна. Когда из первого амбара взяли 470 кг зерна, а из второго в 4 раза больше, то во втором ничего не осталось . Сколько зерна осталось в первом амбаре?

Answer 1

470*4=1880кг взяли со 2-го амбара. 3090-1880-470=740кг зерна осталось в первом амбаре.

Answer 2

Problem Analysis

We are given that there are two barns with a total of 3090 kg of grain. From the first barn, 470 kg of grain is taken, and from the second barn, four times as much grain is taken. After this, there is no grain left in the second barn. We need to determine how much grain is left in the first barn.

Solution

Let's assume that the amount of grain in the second barn is x kg. According to the problem, we know that:

- The total amount of grain in both barns is 3090 kg. - From the first barn, 470 kg of grain is taken. - From the second barn, four times as much grain is taken.

Based on this information, we can set up the following equation:

x + 470 + 4x = 3090

Simplifying the equation, we get:

5x + 470 = 3090

Subtracting 470 from both sides, we have:

5x = 2620

Dividing both sides by 5, we find:

x = 524

Therefore, the amount of grain in the second barn is 524 kg. To find the amount of grain left in the first barn, we subtract the amount taken from the total amount in the first barn:

3090 - 470 = 2620 kg

So, there are 2620 kg of grain left in the first barn.

Answer

There are 2620 kg of grain left in the first barn.
