Problem Analysis

We are given that there were initially 40 liters in a barrel. Some buckets were taken from the barrel, and the amount left in the barrel is 7 times more than what was taken. We need to find out how many liters were taken and how many liters are left in the barrel.

Solution

Let's assume that x liters were taken from the barrel. According to the problem, the amount left in the barrel is 7 times more than what was taken. This means that the amount left in the barrel is 7 times x, or 7x.

We can set up the following equation to represent the given information:

x + 7x = 40

Simplifying the equation, we get:

8x = 40

Dividing both sides of the equation by 8, we find:

x = 5

Therefore, 5 liters were taken from the barrel. To find out how many liters are left in the barrel, we can substitute the value of x into the equation:

7x = 7 * 5 = 35

Therefore, there are 35 liters left in the barrel.

Answer

5 liters were taken from the barrel, and 35 liters are left in the barrel.
