A)The quantity in Column A is greater.
B)The quantity in Column B is greater.
C)The two quantities are equal.
D)The relationship cannot be determined from the information given.
Col. A: \(\frac{\sqrt{3}}{{1 + \sqrt{3}}}\)
Col. B: \(\frac{\sqrt{4}}{{1 + \sqrt{4}}}\)
Cross-multiplying the denominators;
Col. A: \(\sqrt{3}(1+\sqrt{4})\)
Col. B: \(\sqrt{4}(1+\sqrt{3})\)
Col. A: \(\sqrt{3} + \sqrt{12}\)
Col. b: \(\sqrt{4} + \sqrt{12}\)
Subtracting \(\sqrt{12}\) from both the sides;
Col. A: \(\sqrt{3}\)
Col. B: \(\sqrt{4}\)
Hence, option B

This one its preety easy...
Both which from A and B will take more from one?
1+ square root of .33
OR
1+ square root of .25?
Withour knowing how much is the square root of .33 and .25 clearly sqaure root of .25 will be smaller and hence, will take less from 1.
