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

Solution:

An integer is a number with no decimal or fractional part, from the set of negative and positive numbers, including zero.

Jack’s scores in the five successive rounds are 25, - 5, -10, 10 and 15

Total marks obtained by Jack = 25 + (- 5) + (-10) + 10 + 15

= 25 - 5 - 10 + 10 + 15

= 35

Thus, Jack obtained 35 marks in the quiz.
