sir u given divide symbol in this question but here u slove with subtraction how is it possible ?

Question:
What approximate value should come in place of question mark (?)? (Note: You are not expected to calculate the exact value.)

\(\sqrt{624.9995}\) + (4.9989)2 =? ÷ \(\cfrac{1}{4.9900865}\)

Options:
A) 6
B) 50
C) 10
D) 125
E) 15
Solution:
√624.9995 + (4.9989)2 =? ÷\(\frac{1}{4.9900865}\)

Taking approximate values.


⇒ √625 + (5)2 ≈ ? ÷ \(\frac{1}{5}\) 
⇒ 25 +25 ≈ ? × 5 
⇒ ? = \(\frac{50}{5}\) = 10
