Which of the following statement(s) is/are TRUE? \({\rm{I}}.\;\left( {1{\rm{\;}} + {\rm{\;}}\frac{1}{2}} \right)\left( {1{\rm{\;}} + {\rm{\;}}\frac{1}{3}} \right)\left( {1{\rm{\;}} + {\rm{\;}}\frac{1}{4}} \right) \ldots \left( {1{\rm{\;}} + {\rm{\;}}\frac{1}{{998}}} \right) > 497\) \({\rm{II}}.\;14\frac{3}{4}{\rm{\;}} + {\rm{\;}}5\frac{1}{4} - 2\frac{1}{2} > 11\frac{1}{8}{\rm{\;}} + {\rm{\;}}12\frac{3}{8} - 7\frac{1}{4}\)
Both I and II
Statement I: Each factor \(1+\tfrac{1}{n}=\tfrac{n+1}{n}\). The product telescopes:
\[\frac{3}{2} \cdot \frac{4}{3} \cdot \frac{5}{4} \cdots \frac{999}{998} = \frac{999}{2} = 499.5 > 497\] True.
Statement II: LHS = \(14\tfrac{3}{4}+5\tfrac{1}{4}-2\tfrac{1}{2} = 17\tfrac{1}{2}\); RHS = \(11\tfrac{1}{8}+12\tfrac{3}{8}-7\tfrac{1}{4}=16\tfrac{1}{4}\). Since \(17.5 > 16.25\), True.
Hence Both I and II.

If \(\frac{{22\sqrt 2 }}{{4\sqrt 2 - \sqrt {3\, + \,\sqrt 5 }}}\) = \(a + \sqrt 5 b\) , with a, b > 0, then what is the value of (ab) ∶ (a + b)?
The value of \(\frac{1}{{4 - \sqrt {15} }} - \frac{1}{{\sqrt {15} - \sqrt {14} }} + \frac{1}{{\sqrt {14} - \sqrt {13} }} - \frac{1}{{\sqrt {13} - \sqrt {12} }} + \frac{1}{{\sqrt {12} - \sqrt {11} }} - \frac{1}{{\sqrt {11} - \sqrt {10} }} + \frac{1}{{\sqrt {10} - 3}} - \frac{1}{{3 - \sqrt 8 }}\) is:
If x = \(\sqrt {1 + \frac{{\sqrt 3 }}{2}} - \sqrt {1 - \frac{{{\kern 1pt} \sqrt 3 }}{2}} \) , then the value of \(\frac{{\sqrt 3 - x}}{{\sqrt 3 + x}}\) (corrected to two decimal places) is:
