Official Solution: Statement 1: This statement yields three possibilities for P, Q, and R, in some order: {1, 3, 5}, {3, 5, 7}, {5, 7, 9}; it makes no difference which of P, Q, and R is which digit, because they are all added together. • If P, Q, and R are 1, 3, and 5 (in whatever order), then the digit T must be 1. This means the digits aren't distinct, so it is impossible. • If P, Q, and R are 3, 5, and 7 (in whatever order), then T= I. That means S is one of the leftover digits O, 2, 4 6, 8, 9. If these values are plugged into S one at a time, the only one that yields all distinct digits is S 4 (34 + 54+74=162). • If P, Q, and R are 5, 7, and 9 (in whatever order), then T = 2. That means S is one of the leftover digits O, 1, 3, 4, 6, 8. If these values are plugged into S one at a time, the only one that yields all distinct digits is S = 8 (58 + 78 + 98 = 234). • Therefore, there are only two possible values of TUV: 162 and 234. In both cases, the sum of T, U, and V is 9, so (I) is sufficient. Statement 2:
If T = 2, then trial and error will yield a number of working sets of digits yielding different values for TUV. Examples: 58 + 68 + 78 = 204 (T+ U + V = 6); 41 + 71 + 91 203 ( T+ U + V = 5); 49+69 +89 207 (T+ U + V = 9); and several others. Therefore, (2) is insufficient.

Consider A, P Q R are consecutive odd integers. For any sets 1,3,5; 5,7,9; 3,5,7 depending on S values, sum of T, U, V varies. A is not sufficient. Consider B, if T = 2, P, Q ,R could be any distinct digits and S can vary giving different values for sum of T,U,V. Hence, B is insufficient. Combine A,B, if T = 2 then P, Q, R must be 5,7,9 in any order and S must be 8 to satisfy the distinct digits condition giving a unique sum of T,U,V to be 2 + 3 +4 = 5 Answer C.

Answer is E As per 1) we know the numbers in 10s digit are odd consecutive integers...But this enough is not suffieicient...it can be either 3,5,7 or 5,7,1 As per 2) T=2 . Now this alone does not give any surity. As there can be multiple combinations leading to this Using Both We know that P,q,R can only be 5,7,1 as any other combination wont give T=2. But still S can take any value and there can be multiple answers. Hence neither of the statements alone or together are sufficient. Hence the answer is E

1) insufficient if s=1 then v=3 letting p, q and r = 5,7 and 9 respectively then t=2 and u=1 sum of t, u and v= 6 but if we assume s= 2 v=8 and now the sum is 11 2) we do not have to prove this one as when we consider 1st equation, the value of T is 2 in both the cases therefore insufficient E

PS QS RS ____ TUV If the given addition is correct, what is the sum of T, U and V? P, Q, R, S, T, U and V are distinct digits. a) P, Q and R are consecutive odd integers. P,Q,R=1,3,5 OR 3,5,7 OR 5,7,9 NOT SUFFICIENT b) T = 2 THEREFORE THE ANSWER BETWEEN 200 AND 298 P,Q,R COULD BE 6,7,8 OR 7,8,9 NOT SUFFICIENT BOTH TOGETHE NOT SUFFICIENT ANSWER=E

First of all lets note that P,Q,R,S,T,U,V are all distinct digits. St 1) P Q R are consecutive odd integers  this does not give us any information about TUV as PQR could be 1,3,5 or 3,5,7 or 5,7,9. Hence St 1. by itself is not sufficientSt 2) T = 2. Not sufficient by itself as many possibilitiesWe are left with tow options either C or E. Option (C) is correct as a couple of trial and errors shows 234 is TUV and the whole setup is 58+78+98 = 234 Kind Regards, GLadi

E  both not sufficient a. It can be any consecutive numbers (not sufficient) b. T = 2  not sufficient as the previous three numbers P Q Rcan either be (5,7,9 or 7,9,11) combined S can be 1 or 2 and V = 3 or 6 and P Q Rcan either be (5,7,9 or 7,9,11). Still not sufficient

IMO C 1) NS = possible valid combinations for P,Q.R are (1,3,5) & (5,7,9) 2) Clearly NS 1+2) (5,7,) is valid.......Ans C

A. PQR are consecutive odd integers . Here. S is not given and PQR can be any combination  1,3,5 or 3,5,7, each set yielding different results. Hence, not sufficient.
B not sufficient as information about other digits not given
Both,
As T =2, PQR will be 5,7,9 (any order)
However S is not given which will impact the value of U and V. Thus both together are not sufficient.
Thus, answer is E

Hi We need to find sum of T, U and V As per your solution, sum of T, U,V = 1+5+6 =12 Where as official solutions gives the sum = 5 , 6... Since we are getting more than one value of sum, the sum of T, U and V cannot be find uniquely. Statement 2 is INSUFFICIENT. Hope it is clear now. saban wrote: gmatbusters wrote: Official Solution: Statement 1: This statement yields three possibilities for P, Q, and R, in some order: {1, 3, 5}, {3, 5, 7}, {5, 7, 9}; it makes no difference which of P, Q, and R is which digit, because they are all added together. • If P, Q, and R are 1, 3, and 5 (in whatever order), then the digit T must be 1.

Recheck your assumption, All P, Q, R, S, T, U, V are distinct. As per your assumption: " TUV P, Q, R can be (3,5,7)

On my second go, I somehow didn't take the PS, QS, RS as two digit numbers at all. Rather I considered them to be product of the digits. How can we rule out my possibility with nothing given in the question?
