Answer:
One problem is the inaccessibility to meet the demands of your consumers. If you're not being aware of what products is more needed by the customers, then you are selling the wrong product that can lead to the failure of the business due to low income. Another is the capital. When a businessman starts his business with a low capital, there's a chance that this would lead to failure. However, this depends on how small or big the business is. Another important problem is the competition that makes a business fail. Due to many competitors that sell the products, that is a big threat to a business of someone selling the same products.
