G is the guardian of M ,a minor . G sells the property Of M worth 20,000   for only 15,000 . The contract of sale can not be rescinded.

The statement seems to be a legal scenario. Here's the step by step analysis:

1. G is the guardian of M, a minor. In many jurisdictions, a guardian has the legal authority to manage the property of the minor.

2. G sells the property of M worth 20,000 for only 15,000. This implies that G sold the property at a price lower than its actual value.

3. The contract of sale cannot be rescinded. This means that the sale cannot be cancelled or reversed.

However, the validity of this statement can vary depending on the specific laws of the jurisdiction where this situation is taking place. In some jurisdictions, a guardian may be required to obtain court approval before selling a minor's property, especially if the sale is not in the best interest of the minor. If G sold the property without court approval or at a price significantly lower than its actual value, the sale might be considered invalid and could potentially be rescinded.

It's also important to note that this is a general analysis and the actual legal implications can vary greatly depending on the specific details of the situation and the laws of the jurisdiction.
