Answer 1

Visualizing the question : 1 Mark
Total Score : 1 Mark
Average : 2 Marks

Jack’s scores in five successive rounds are 25, −5, −10, 15, and 10. Total score of Jack at the end will be the sum of these scores.

Therefore, Jack’s total score at the end
$=25+(-5)+(-10)+15+10$

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

$=35$

Average Score

$=\frac{35}{5}$

$=7$
