\( \Large \sqrt{624.9995}+ \left(4.9989\right)^{2} = ? \div \frac{1}{4.9900865} \)

A) 6
B) 50
C) 10
D) 125

Correct Answer:



C) 10

Description for Correct answer:
\( \Large \sqrt{624.9995}+ \left(4.9989\right)^{2} = ? \div \frac{1}{4.9900865} \)

Taking approximate values,

=> \( \Large \sqrt{625}+ \left(5\right)^{2}=? \div \frac{1}{5} \)

=> \( \Large 25+25 = ? \times 5 \)

=> \( \Large ? = \frac{50}{5} \) = 10
