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?
It is given in the question that,
Scores of Jack in 5 successive rounds = 25, -5, -10, 15 and 10
Therefore,
Total score of Jack at the and will be the sum of scores of 5 successive rounds
Therefore,
Total score of Jack = 25 + (-5) + (-10) + 15 + 10
= 25 – 5 – 10 + 15 + 10
= 25 – 15 + 15 + 10
= 25 + 10
= 35
