# 2. In a quiz, positive marks are given for correct answers and negative marks are given for incorrect answers. If Jack’s scores in five successive rounds were 25, – 5, – 10, 15 and 10, what was his total at the end?

Given, Jack’s scores in five successive rounds are $25, - 5, - 10, 15\ and\ 10$
Therefore, his total score = $\\ 25 +(- 5) +(- 10)+ 15+10$
$\\ = 25 - 5 - 10+ 15+10 \\ = 35$
His total score at the end was  $35$
