Mrs. ross, a teacher, wanted to measure the iq of the newly admitted students in her class. while using william stern's method for calculating intelligence, she found out that sarah, a ten-year-old girl, had the mental age of a 14 year old. what is sarah's intelligence score?

140

Explanation:

William Stern, the German psychologist, devised the fundamental definition of intelligence quotient or IQ in 1912. He defined IQ as a ratio of an estimated mental age and actual age by multiplying it with 100.  The equation can be reached thus:

100×(mental age/actual age).

In case of Sara, her actual age is 10 and her mental age is 14. Therefore, her  IQ is equal to 100 x 14/10 = 140
