A) \[5I\,\text{and}\,I\]
B) \[5I\,\text{and}\,3I\]
C) \[9I\,\text{and}\,3I\]
D) \[9I\,\text{and}\,I\]
Correct Answer: D
Solution :
\[{{I}_{\max }}={{I}_{1}}+{{I}_{2}}+2\sqrt{{{I}_{1}}}\,\sqrt{{{I}_{2}}}\] \[=I+4I+2\sqrt{I}\,\sqrt{4I}=9I\] \[{{I}_{\min }}={{I}_{1}}+{{I}_{2}}-2\sqrt{{{I}_{1}}}\,\sqrt{{{I}_{2}}}\] \[=I+4I-2\sqrt{I}.\,\sqrt{4I}=I\]You need to login to perform this action.
