in a quiz team A scored 45,-50and75 in three successive rounds whereas B scored 45,50 and +25 which team scored more and how much

Total score of team A = 75+50+45 = 170
Total score of team B = 50+45+25 = 120
Therefore difference = 170-120 = 50

Ans : Team A scored more than B by 50 points

Score of team A = 45 + (-50) + 75
                           = 45 - 50 + 75
                           = (-5) + 75
                           = 70
Score of team B = 45 + 50 + (+25)
                           = 45 + 50 + 25
                           = 95 + 25
                           = 120
120 - 70
= 50
Therefore, team B scored more than team A by 50 points.

Score of team A=45+(-50)=75
                          =45-50+75
                          =70
Score of team B=45+50(+25)
                          =45+50+25
                          =120
=120-70
Therefore,Team B scored more Team A by 50 points    

Score of Team A = 45+(-50)+75 =70
