The simplified value of 5 + 11 + 19 + 29 + 49 = ?

Answer: Option A

$$\begin{array}{rl}& \text{According to question,}\\ & \sqrt{5+\sqrt{11+\sqrt{19+\sqrt{29+\sqrt{49}}}}}\\ & \Rightarrow \sqrt{5+\sqrt{11+\sqrt{19+\sqrt{29+7}}}}\\ & \Rightarrow \sqrt{5+\sqrt{11+\sqrt{19+\sqrt{36}}}}\\ & \Rightarrow \sqrt{5+\sqrt{11+\sqrt{19+6}}}\\ & \Rightarrow \sqrt{5+\sqrt{11+\sqrt{25}}}\\ & \Rightarrow \sqrt{5+\sqrt{11+5}}\\ & \Rightarrow \sqrt{5+\sqrt{16}}\\ & \Rightarrow \sqrt{5+4}\\ & \Rightarrow \sqrt{9}\\ & \Rightarrow 3\end{array}$$
