To find:

The total score at the end.​

Solution:

It is given that the scores in five successive rounds were 25,-5,-10, 15 and 10. So, the sum of the scores at the end is:

`Sum=25+(-5)+(-10)+15+10`

`Sum=(25+15+10)+(-5-10)`

`Sum=50+(-15)`

`Sum=50-15`

`Sum=35`

Therefore, the total score at the end. is 35.
