Correct Answer: $\frac{12}{5}$

Solution :
Given: $\angle PQR = 90°$ and $PQ:QR = 3:4$
Let, $PQ = 3k$, $QR = 4k$.
As $PR$ is the hypotenuse, $PR = \sqrt{(3k^{2} + 4k^{2})}=5k$
$\sin P = \frac{QR}{PR} = \frac{4k}{5k}=\frac{4}{5}$
$\sin Q = \sin 90° = 1$
$\sin R = \frac{PQ}{PR} = \frac{3k}{5k}=\frac{3}{5}$

Correct Answer: $\frac{6070}{14973}$

Solution : Given:
 $S=\frac{1}{1×3×5}+\frac{1}{1×4}+\frac{1}{3×5×7}+\frac{1}{4×7}+\frac{1}{5×7×9}+\frac{1}{7×10}+....$ Up to 20 terms.
Rewriting it like,
$\frac{1}{1×3×5}+\frac{1}{3×5×7}+\frac{1}{5×7×9}+...+\frac{1}{1×4}+\frac{1}{4×7}+\frac{1}{7×10}+...$Up to 20 terms.
$=\frac{1}{4}[\frac{1}{1×3}-\frac{1}{3×5}+\frac{1}{3×5}-\frac{1}{5×7}+\frac{1}{5×7}-\frac{1}{7×9}+...–\frac{1}{21×23}]+\frac{1}{3}[1-\frac{1}{4}+\frac{1}{4}-\frac{1}{7}+\frac{1}{7}-\frac{1}{10}+...-\frac{1}{31}]$
It will cancel out most of the terms except the first and last term.
$=\frac{1}{4}[\frac{1}{1×3}-\frac{1}{21×23}]+\frac{1}{3}[1-\frac{1}{31}]$
$=\frac{40}{483}+\frac{10}{31}$
$=\frac{6070}{14973}$
Hence, the correct answer is $\frac{6070}{14973}$.
