Answer 1

$\bullet$ In round $1$, Samuel scored $150$ points.
$\therefore$ Total score of Samuel after round $1$ $=150$ points

$\bullet$ In round $2$, Samuel scored $-200$ points, i.e., Samuel got penalty points for giving wrong answers.
$\therefore$ Total score of Samuel after round $2$ $=150+(-200)$ points
$=-50$ points

$\bullet$ In round $3$, Samuel scored $100$ points.
$\therefore$ Total score of Samuel after round $3$ $=-50+100$ points
$=50$ points

Hence, the total score of Samuel after completing all the three rounds of the quiz is $\underset{–}{50\text{points}}$.
