Explanation Given: When administering a standard intelligence quotient (IQ) test, One-third of the score has to be more than 12 units above 100 or more than 12 units below 100 . Formula Used: If a , b and c are real numbers and a < b Then a + c < b + c Calculation: Let score is denoted by the variable x . One-third of scores are more than 12 units above 100 . Mathematically it can be written as the x > 100 + 12 If a , b and c are real numbers and a > b Then a + c > b + c Use the above property and add − 100 in the above inequality x > 100 + 12 x − 100 > 12 …
