Direction: What approximate value should come in place of question mark (?) in the question? |
A) 53
B) 16
C) 28
D) 43
E) 48
Correct Answer: D
Solution :
\[{{(9.001)}^{3}}=(?-3.3)\times 89.897\div \sqrt[4]{624.99}\] or, \[{{(9)}^{3}}\approx (?-3.3)\times 90\div \sqrt[4]{625}\] \[(\sqrt[4]{625}=\sqrt[4]{{{5}^{4}}})\] \[=(?-3.3)\times \frac{90}{5}\] \[=18\times ?-3.3\times 18=18\times ?-59.4\] \[or,?\approx \frac{790}{18}\approx 43\]You need to login to perform this action.
