$\sqrt{6+\sqrt{6+\sqrt{6+\cdots}}} = ?$

In a college,$\frac{1}{5}$ of the girls and $\frac{1}{8}$ of the boys took part in a social camp. The fraction of the total students in the college who took part in the camp is:

$\sqrt{2601} - \sqrt{1156} + \sqrt{484} = ?$

The quotient arising from a division of a number by $62$ is $463$ and the remainder is $60$. What is the number?

The expression $\frac{8.25 \times 8.25 + 6.75 \times 6.75 - 2 \times 8.25 \times 6.75}{8.25 \times 8.25 - 6.75 \times 6.75}$ when simplified equals:
