Does set S contain any even numbers
Does set S contain any even numbers?
I. There are no prime numbers in S.
II. There are no multiples of 4 in S.
Ques- The question asks whether there are any even numbers in the set S so as per stmt I -no primes i.e remaining no’s that can be a part of S (1,4,6,8,9) – Sufficient
stmnt II no multiples of 4 – remaining no’s- – 6,7,10,12 makes the stmnt sufficient
where am i going wrong?
Hi Ria,
This is a YES/NO data sufficiency. You should always try to disprove and not to prove the statements to be sufficient.
Statement 1 : What is set S has all odd numbers, for eg : (1,3,5,7,9). So it is possible to get a YES and a NO.
Statement 2 : Again we can have a set (1,3,5,7,9). Insufficient.
Combining the statements : Again not sufficient, since we can have any set with fractions or an example of a set with integers (1,9, 15). Note that we have no information about the number of elements in the set.
Hope this helps!
