I got the answer as (E) ...
I approached it in this way. If "I" is itallian , "T" is telefonica , "x" is both italian and telephonica , "y" is neither italian nor telephonica.
So , I+T-x + y = 10
Statement 1 : I-x +y=2 or T = 8 , but we want T-x . Insufficient
Statement 2 : y=0 , so I+T-x = 10 , but we want T-x . Insufficient.
Combining both statements , T-x = 10-I=10-2+x-y or T-2x=8 (as y=0) . Not helpful as we want T-x.
Somebody please correct me , if I made a mistake here. I have assumed that there are people who do not belong telephonica or are Italian , because nothing is specified in the question stem. It is only statement 2 that is mandating such a condition.
I believe that statement 2 translates to Neither = 0
Question Stem tells us that out of the 10 people who finished first, 4 were Italians and 6 were not. Moreover it tells us that 8 are members of Telefonica and 2 are not.
Statement 1 tells us that out of the 4 Italians 2 are members of telefonica are 2 are not. Since there is a total of 8 members of Tefefonica it means that 2 of them are Italians and the other 6 are not. Sufficient
Statement 2 tells us that people who are neither Italian or member of telefonica is 0. Which is Sufficient to answer the Question.
Therefore D.
