| Directions: What value will come in place of question mark (?) in the following questions? |
| \[92\times 576\div (2\sqrt{1296})={{?}^{3}}+\sqrt{49}\] |
A) 3
B) \[{{9}^{2}}\]
C) 9
D) 27
E) None of these
Correct Answer: C
Solution :
| \[92\times 576\div (2\sqrt{1296})={{?}^{3}}+\sqrt{49}\] |
| \[\Rightarrow \] \[\frac{92\times 576}{2\times 36}={{?}^{3}}+7\] |
| \[\Rightarrow \] \[736={{?}^{3}}+7\] |
| \[\Rightarrow \] \[{{?}^{3}}=736-7=729={{9}^{3}}\] |
| \[\Rightarrow \] \[?=9\] |
