Which of the following numbers is the greatest?

What value will come in place of the question mark (?) in the following question? (You are not expected to calculate the exact value)
$10^{3} \times 100^{3} + 999999999 = 10^{?} + 10^{?}$

$A$ sum of $Rs. 1360$ has been divided among $A, B$ and $C$ such that $A$ gets $\frac{2}{3}$ of what $B$ gets and $B$ gets $\frac{1}{4}$ of what $C$ gets. $B$'s share is (in $Rs.$)

Simplify $\frac{0.2 \times 0.2 + 0.2 \times 0.02}{0.044}$

If $\frac{x^{24}+1}{x^{12}}=7$,then find the value of $\frac{x^{72}+1}{x^{36}}$.

The value of $\frac{1}{2+\frac{1}{2+\frac{1}{2-\frac{1}{2}}}}$ is
