A) 1
B) \[\frac{4}{9}\]
C) \[\frac{5}{9}\]
D) 2
Correct Answer: A
Solution :
\[\frac{b}{a}=0.25\Rightarrow b=0.25\,a\] \[\therefore \] \[\frac{2\text{a}-b}{2\text{a}+b}+\frac{2}{9}=\frac{2\text{a}-0.25\text{a}}{2\text{a}+0.25\text{a}}+\frac{2}{9}\] \[=\frac{1.75\text{a}}{2.25\text{a}}+\frac{2}{9}=\frac{7}{9}+\frac{2}{9}=1\]
