Ice hockey teams R and U played against each other in the final games of numerous championships. Which of the teams won more than 1/2 of these games?
(1) The total number of games teams R and U played against each other in finals is 30.
(2) Team R scored 128 goals in these matches, and Team U scored 203 goals in these matches.
we need to find out which team won more than 1/2 of the finals.
Statement 1 : by knowing both the team played in 30 finals we cannot find how many matches each team win. statement 1 insufficient.
statement 2 : Team R scored = 128 goals and Team U scored = 203 goals
suppose they scored 100 matches
scenario 1 : Team u scored 203 goals in 10 matches and won 10 matches and Team R scored 128 goals in rest of 90 matches
and won 90.
scenario 2 : Team u scored 203 goals in 90 matches and won all 90 matches and Team R scored 128 goals in rest of 10 matches
and won only 10.
so cannot find which team won more than 1/2 of the games.
therefore statement 2 insufficient.
same when combined instead of 100 just put 30 . so combined also insufficient . Hence answer is E .
