Direction: What will come in place of question mark (?) in the following questions? |
A) \[\pm 11\]
B) \[\pm 8\]
C) \[\pm 6\]
D) \[\pm 7\]
E) \[\pm 5\]
Correct Answer: C
Solution :
\[[{{(11025\div 9)}^{\frac{1}{2}}}+{{(8019\div 11)}^{\frac{1}{2}}}]={{?}^{2}}+26\] or,\[{{?}^{2}}=[{{(1225)}^{\frac{1}{2}}}+{{(729)}^{\frac{1}{2}}}]-26\] \[=(35+27)-26=62-26=36\] \[\therefore \]\[?=\pm \sqrt{36}=\pm 6\]You need to login to perform this action.
