In a quiz, positive marks are given for correct answers and negative marks are given for incorrect answers.

Jack's scores in five successive rounds were $25,\ -5,\ -10,\ 15$ and $10$

To do:

We have to find his total at the end.

Solution:

Scores of Jack in five successive rounds were $25,\ -5,\ -10,\ 15,\ 10$.

Total sum of the scores at the end $=25+( -5)+( -10)+15+10$

$=25-5-10+15+10$

$=35$

Hence, Jack's score at the end is $35$ marks.
