A) 3
B) 5
C) 9
D) 8
E) 10
Correct Answer: D
Solution :
\[\frac{a+2}{2}=\sqrt{2a}+1\] \[\Rightarrow \] \[\frac{a}{2}+1=\sqrt{2a}+1\] \[\Rightarrow \] \[\frac{a}{2}=\sqrt{2a}\] \[\Rightarrow \] \[\frac{{{a}^{2}}}{4}=2a\] \[\Rightarrow \] \[a\left( \frac{a}{4}-2 \right)=0\] \[\Rightarrow \] \[a=0,a=8\]
