Final answer:
In a sale by both sample and description, typically, the description takes precedence over the sample as it represents the full quantity of goods, but this can vary based on the contract terms and jurisdiction.
Step-by-step explanation:
When there is a sale by both sample and description, the general principle under contract law is that both the sample and description should correspond to what is being sold. However, when a conflict arises between the two, precedence is usually given to the description, as it is considered more representative of the full quantity of goods. This might vary depending on the jurisdiction and the specific terms and conditions agreed upon in the contract of sale. In some cases, terms may dictate that the sample takes precedence or that both sample and description must be taken into account. It is important to refer to the terms of the contract to understand which would take precedence in any given situation.
