Answer & Solution
Correct Answer:
Option
E
(Students from Towns C and D) : (Students from Towns A, D and E)
$$\eqalign{ & = \frac{\left(17.5+42.5\right)\times1000}{\left(40+42.5+35\right)\times1000} \cr & = \frac{60}{117.5} \cr & = \frac{600}{1175} \cr & = \frac{24}{47} \cr & = 24 : 47 \cr} $$
$$\eqalign{ & = \frac{\left(17.5+42.5\right)\times1000}{\left(40+42.5+35\right)\times1000} \cr & = \frac{60}{117.5} \cr & = \frac{600}{1175} \cr & = \frac{24}{47} \cr & = 24 : 47 \cr} $$
