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) 9
B) 6
C) 7
D) 8
E) 11
Correct Answer: C
Solution :
\[24.87\sqrt{?}+\sqrt{2025}+\sqrt{7225}=152.371\times 8.756\] or, \[25\sqrt{?}+45+85\approx 152\times 9=1368\] or, \[25\sqrt{?}\approx 1368-130\] or, \[\sqrt{?}\approx \frac{1238}{25}\approx 49.52\] \[\therefore ?\approx {{(49)}^{\frac{1}{2}}}=7\]You need to login to perform this action.
