There are 50 horses and 7 poles all must be tied to the each pole should have only odd number of say how will tie them?

The Problem:

You can't tie an even number of horses to a pole and have a total of 50 horses. Here's why:

* Odd + Odd = Even: If you tie an odd number of horses to each pole, and you have multiple poles, the total number of horses will always be even.

The Solution:

You need to think outside the box a little. Here's how to tie the horses:

1. Tie 1 horse to each of the 7 poles. This uses up 7 horses.

2. Tie the remaining 43 horses to one of the poles. You can tie them all to the same pole, as long as the total on that pole is still odd.

Why this works:

* You've tied an odd number of horses to each pole (1 or 43).

* The total number of horses is still 50.
