Direction: What approximate value should come in place of question mark (?) in the the question? (You are not expected to calculate the exact value.) |
A) 4
B) 5
C) 3
D) 7
E) 9
Correct Answer: B
Solution :
\[\begin{align} & \sqrt[3]{?}\times 5.68+102.78\times 10.876- \\ & 98.762\times 12.001=695 \\ \end{align}\] or, \[\sqrt[3]{?}\times 6+103\times 11-99\times 12\approx 695\] \[\sqrt[3]{?}\times 6\approx 695+99\times 12-103\times 11\] \[=1883-1133\] Or, \[\sqrt[3]{?}\approx \frac{750}{6}=125\] \[\therefore ?\approx 5\]You need to login to perform this action.
