The trick here is that -

Between first 65 and last 65 -> 30 matched will overlap.
Since the team played only 100 matches,
=> 78-30 =48 < 50
Hence together also it will case will not be sufficient.
Option E !

A sports team played 100 games last season. Did this team win at least half of the games it played last season?

(1) The team won 60% of its first 65 games last season. The team won 0.6*65 = 39 of its first 65 games, we know nothing about the last 35 games. Not sufficient.

(2) The team won 60% of its last 65 games last season. The team won 0.6*65 = 39 of its last 65 games, we know nothing about the first 35 games. Not sufficient.

(1)+(2) Maximum number of games the team could have won is 39 + 39 = 78, for example if it won first and last 39 games. Minimum number of games the team could have won is 30 + 9 + 9 = 48, for example if it won first and last 9 games and 30 games which are the overlap of first 65 games and last 65 games. Not sufficient.

Answer: E.

Hope it's clear.

Hi Bunuel,

I have a question. How is this true: Maximum number of games the team could have won is 39 + 39 = 78

From 1+2, I know that
1---------------won-------------------35-------4 won-------- 65------------------------100
100------------------------------------65---------4 won-------35---------won------------1

Total won = 35+4+35 = 74. The overlapping region is 4 and it will be counted once. How is your total 78. Please clarify.
