In a school there are 96 teachers, out of which \(\frac{3}{8}\)th teaches High school classes. If \(\frac{2}{9}\)th of the High school teachers are Mathematics teachers. then the number of High school teachers who don't teach Mathematics are: Correct Answer 28

Given:

Number of school teachers = 96

High school teachers = 3/8th

Mathematics teachers = 2/9th of high school teachers

Calculation:      

Number of high school teachers = 3/8 of 96 = 36

⇒ Mathematics teacher = 2/9 of 36 = 8

⇒ Non mathematics teacher = 36 - 8 = 28

∴ The number of High school teachers who don't teach Mathematics are 28

The correct option is 3 i.e. 28
