\( \Large 63.9872 \times 9449.8780 \div 243.0034 = \left(?\right)^{2} \)

A) 2489
B) 2500
C) 50
D) 45

Correct Answer:



C) 50

Description for Correct answer:
\( \Large \left(?\right)^{2} = 63.9872 \times 9449.8780 \div 243.0034 \)

Taking approximate integral values,

\( \Large \left(?\right) = 64 \times 9450 \div 240 \)

=\( \Large \frac{64 \times 9450}{240} = 2520 \) = 2500

Therefore, \( \Large ? = \sqrt{2500} \) = 50
