Does memory affect IQ scores?

What is the mental age of a person with an IQ of 60?

An IQ of 60 typically falls into the mild intellectual disability range (IQ 50-69) and corresponds to a mental age for adults of roughly 9 to under 12 years old, meaning their cognitive skills are similar to an average 9-12 year old child, enabling them to learn basic academic skills and practical life skills but facing significant learning challenges. While the old formula (Mental Age / Chronological Age x 100) isn't used for adults, an IQ of 60 indicates cognitive functioning equivalent to a younger child, allowing for functional independence in daily life, work, and social relationships, although it's considered borderline or mild impairment.
