Which of the following represents the greatest value?
(A) \(\frac{\sqrt{2}}{\sqrt{3}} + \frac{\sqrt{3}}{\sqrt{4}}+\frac{\sqrt{4}}{\sqrt{5}}+\frac{\sqrt{5}}{\sqrt{6}}\)
(B) \(\frac{2}{3} + \frac{3}{4} + \frac{4}{5} +\frac{5}{6}\)
(C) \(\frac{2^2}{3^2} + \frac{3^2}{4^2} + \frac{4^2}{5^2} + \frac{5^2}{6^2}\)
(D) \(1-\frac{1}{3} + \frac{4}{5} - \frac{3}{4}\)
(E) \(1-\frac{3}{4} + \frac{4}{5} + \frac{1}{3}\)

I think for most people the only confusing options will be A and B.
You can compare fractions very easily by making either their denominator or numerator same.
Say I want to compare \(\sqrt{2} / \sqrt{3}\) with 2/3.
I just multiply and divide \(\sqrt{2} / \sqrt{3}\) by \(\sqrt{2}\) to get 2/\(\sqrt{6}\).
Since \(\sqrt{6}\) is less than 3, 2/\(\sqrt{6}\) (i.e. \(\sqrt{2} / \sqrt{3}\)) is greater than 2/3.
Similarly, all terms of option A will be greater than all corresponding terms of option B.
Perfect example of how complicated looking questions are also based on very fundamental concepts.

I could make direct comparison between A, B and C and locked on A because the difference between numerator & denominator of individual term in A are smaller than that of B and C.
D: 1-0.3+0.8-0.75<1
E: 1-0.75+0.8+0.3= 1.5 approx
A: Every term is definitely more than 0.5 because the denominator was less than twice. Thus
A> 0.5+0.5+0.5+0.5=2
Ans: "A"
