(1) None of the 3 numbers that are facing up is divisible by 3
(2) Of the numbers that are facing up, 2, but not all 3, are equal

Stmt 1 says that it can 1,2,4,5 then we can have 4,4,4 or 5,5,2 not suff.
Stmt 2 says 2 are year equal not three, it can mean 3,3,6 or 5,5,2. not suff

Hence C is the answer. as we rule out none of the numbers are divisible by 3.

(1) None of the 3 numbers that are facing up is divisible by 3
3's & 6's are out - The result can be achieved with (5,2,5)/ (4,4,4) -Insufficient

(2) Of the numbers that are facing up, 2, but not all 3, are equal
Possibilities for the condition are (5,5,2)/ (3,3,6) - Insufficient

Combining Statements 1) & 2) Only possible was of getting the sum is (5,5,2)

Answer C)

(2) Of the numbers that are facing up, 2, but not all 3, are equal


Sides of the dices are 1,2,3,4,5,and 6

(1)Among the above dice sides,sides divisible by 3 are 3 and 6,so facing up numbers must be among 1,2,4,and 5,so to get sum the three dice sides could be 4,4,and 4 or 5,5,2 .......>Not Sufficient
(2)Sum of the at most 2 two equal sides that are facing up and another 1 side may happen with many combination of dice numbers,example-(3,3,6)(5,5,2), .........>Not sufficient

(1)+(2) only combination of 5,5,and 2 sides on top of the dice sum up to 12,Sufficient

Correct Answer C

We are given that three dice (numbered 1 to 6) are tossed and that the sum of the three numbers facing up is 12. We need to determine whether one of these numbers is 5.

Statement One Alone:

None of the 3 numbers that are facing up is divisible by 3.

The information in statement one is not sufficient to answer the question. The numbers facing up could be 4, 4, and 4, and none of these numbers are 5. However, the numbers facing up could be 5, 5, and 2, and at least one of these numbers is 5. Statement one alone is not sufficient to answer the question. We can eliminate answer choices A and D.

Statement Two Alone:

Of the numbers that are facing up, 2, but not all 3, are equal.

The information in statement two is not sufficient to answer the question. The numbers facing up could be 3, 3, and 6, and none of these numbers are 5. However, the numbers facing up could be 5, 5, and 2, and at least one of these numbers is 5. Statement two alone is not sufficient to answer the question. We can eliminate answer choice B.

Statements One and Two Together:

Using the information from statements one and two, we can determine that the only way to obtain a sum of 12, when none of the numbers are divisible by 3 and when exactly two of the numbers are equal, is if the numbers facing up are 5, 5, and 2. Thus, at least one of the numbers is 5.

Answer: C

Stmt 1 Alone - Not Sufficient:
(5+5+2)=12 (Is at least 1 of these numbers 5? --> YES)
(4+4+4)=12 (Is at least 1 of these numbers 5? --> NO)
Stmt 2 Alone - Not Sufficient:
(3+3+6)=12 ((Is at least 1 of these numbers 5? --> NO)
(5+5+2)=12 ((Is at least 1 of these numbers 5? --> YES)
Stmt 1 & 2 together (Sufficient)
(6,6,x) not possible combo
(5,5,2) Possible - (Is at least 1 of these numbers 5? --> YES)
(4,4,4) not possible combo (stmt2 violated)
(3,3,6) not possible combo (stmt1 violated)
(2,2,x) not possible combo
(1,1,x) not possible combo.
