more zeros

by sanju09 » Thu Apr 22, 2010 4:24 am
The product of five integers is zero. How many of the five integers are zero?

(1) There are more zeros than the non-zero integers in the given list of five integers.

(2) Product of any two of the five integers is zero.

statement 1 : inconclusive. can be 4 zeros and 1 non zero. can be 3 zeros and 2 non zeros.

statement 2 : sufficient. each number has to zero in order to fulfill this condition.

IMO B.

(1) There are more zeros than the non-zero integers in the given list of five integers.
0, 0, 0, 2, 3
0, 0, 0, 0, 4
0, 0, 0, 0, 0

Insufficient

(2) Product of any two of the five integers is zero.

0, 0, 0, 0, 4
0, 0, 0, 0, 0

Can I consider all zero's? If can, then E

If cannot, then B

IMO C

(1)
More zeroes than the non zeroes implies it could be 3 or 4. Hence Insuff

(2)
4 could be 0 or all could be zero

Combined
(1) implies there is at least 1 non zero integer, and from 2 we can gather that there are 4

Hence C
Whether you think you can or can't, you're right.

Why cannot all five be zero, according to statement (1)?

Well because of the following statement I did conclude the above
(1) There are more zeros than the non-zero integers in the given list of five integers.
But on second thought it can be 5 and 0 as 5>0. Hmm, the language did confuse me.
Now I think its E
