IQ is not dependent on age. Regardless of age, a person who possessed an IQ of 75 would be Mildly Retarded, or very close to that.
The IQ would be 100.
If the boy's chronological age and mental age are equal, his IQ would be assumed to be 100. (Using chronological age x IQ/100 as the template).
Since IQ (intelligence quotient) refers to the apparent mental age compared to the current age, an IQ cannot be applied to a vegetable since this would require the presence of observable intelligence. If anything, a vegetable would have an IQ of 0.
IQ is traditionally the ratio of mental age to physical age multiplied by 100. At the extremes, it's largely meaningless - an IQ of 1 would mean a 100 year old person with a mental age of 1. The average IQ (Intelligence Quotient) is between 90 - 110. So for one to have an IQ of 1 would be highly improbable.
What it roughly means is that a person at age 5 would have the intelectual development of an average child (one with an IQ of 100) of age 6.6, at age 10 would be intellectually equal to an average child of age 13.2, and at age 15 would be mentally equal to an average person who was almost 20. In broader terms, someone with an IQ of 132 would be considered "gifted" but not a genius. An IQ of 132 would supposedly place a person 2 standard deviations above the average. This translates to being in the top 2.3% of the population in intelligence. A genius, by contrast would have an IQ of at least 145 and be in the top 0.3% of the population.
The IQ would be 100.
According to the bell curve, I would think so.
The 12-year-old would be said to have an IQ of 75. This is calculated by dividing the mental age (equivalent to that of an average 9-year-old) by the chronological age (12) and multiplying by 100.

IQ has nothing to do with your age or gender. Your IQ would be the same no matter what age you were. And an average IQ is 100. So yours is slightly above average.
Her IQ can be calculated using the formula: (mental age / chronological age) * 100. In this case, her IQ would be (20 / 10) * 100 = 200.
IQ= MA/CA x 100 IQ= 10/8 x 100 IQ= 1.25 x 100 IQ= 125

100 is the average IQ - for any age. One's IQ is graded against the average for one's age. So a person with an IQ of 100 at age 10, could well have the same IQ at ages 20, 30 or any other age. Significantly above or below 100 is note-worthy.

Good IQ tests, administered properly, are not age-dependent. An average IQ, by definition, is 100, so a score of 124, at any age, is well above average. Congratulations!
