Show Answer

Answer:

Correct Answer: B

Solution:

Let group of teacher, engineers, doctor and salesman denoted by T, E, D, and S, respectively, According to the question. $ 25T+20E+18D+12S=1330 $ Given, $ 5T=4E $
$ \Rightarrow $ $ T=\frac{4}{5}E $

$ \Rightarrow $ $ 12E=9D $
$ \Rightarrow $ $ D=\frac{12}{9}E $

$ \Rightarrow $ $ 6D=8S $ $ S=\frac{6}{8}D=\frac{6}{8}\times \frac{12}{9}E=E $

$ \therefore $ $ 25\times \frac{4}{5}E+20E+18\times \frac{12}{9}E+12E=1330 $

$ \therefore $ $ 76E=1330 $

$ \Rightarrow $ $ E=17.50 $
