Sally's mental age is 12, and her chronological age is 10. What is her intelligence quotient?

To calculate Sally's intelligence quotient (IQ), you can use the formula that relates mental age and chronological age. The formula is:

IQ = (Mental Age / Chronological Age) × 100

In this case, Sally's mental age is 12, and her chronological age is 10. Plugging these values into the formula:

IQ = (12 / 10) × 100

This simplifies to:

IQ = 1.2 × 100 = 120

Thus, Sally's intelligence quotient is 120. This score indicates that her cognitive abilities are above average for her chronological age, as she has a mental age that exceeds her actual age. An IQ of 120 reflects a performance level higher than what is typically expected for someone her age.
