Cow, the second son gets two cows, the third son gets three cows, and the fourth son gets four cows. If the total number of cows in the herd is a multiple of 10, what is the smallest possible number of cows in the herd?

Let's assume the number of cows in the herd is x.

According to the given information, the sons receive 1 + 2 + 3 + 4 = 10 cows in total.

Since the total number of cows in the herd is a multiple of 10, we can express it as 10k, where k is a positive integer.

So, we have x = 10k.

Now let's consider the equation for the total number of cows given to the sons: 1 + 2 + 3 + 4 = 10.

We can rewrite this equation as 10k = 10.

Dividing both sides of the equation by 10, we get k = 1.

Substituting k = 1 back into the equation x = 10k, we find that x = 10(1) = 10.

Therefore, the smallest possible number of cows in the herd is 10.
