Video Summary

The problem involves deducing a grandmother's age based on incorrect guesses by her grandchildren. Guesses were 75, 78, and 81, each wrong by 1, 2, or 4 years. By adjusting for the error, two possible ages are found: 79 and 77. Therefore, the exact age cannot be determined from the provided information, making the solution indeterminate.
