Hi Amsey,
Only by seeing x-y = 6 you cannot conclude because x = 3 and y = -3 can yield u 6 and also serve as yes for the main q.So only by seeing this statement we cannot conclude anyting.
Well, answer says B...but IMO, must be D...
look at as what exactly is being asked...
IS X = |Y ???
and equation is x-y = 6...
there is a direct answer to this, which says "NO"...its not possible that X| = |Y...
What Deepak has stated is clear. Lets consider two values of x and y
x=3, y =-3
x - y =6 -- well x=|y
x=9, y=3
x - y =6 -- x| != y
thus , we cant determine anything from this equality.
HTH
I'm sorry but this is DS?
and stem is made based on some facts, if not so they would have asked
is x = y or something?
To me, is X = Y ??
yields an result from the equation, x-y = 6 and answer is NO..
if you could give a condition where it doesn't hold true, i'll be convinced
cheers
Deepak,
Whats the problem if x=y=0? Plz elaborate.
Ans for the below one :
Is x=y?
(1) x - y = 6
(2) x + y = 0
statement 1 :
==========
x -y = 6 .Can have multiple values.
Statement 2:
===========
x = -y which gives x = y provided x and y is not equal to zero.So statement 2 is not suff.
But combining both, we get x = 3 and y = -3 which will give us the result.
Please post the OA
E should be the ans. whats the OA?
Clearly none alone is sufficient. Lets consider them together.
Lets say Sal of 80 emp last yr was X
Sal of 20 emp last yr was Y
Avg Sal = (X + Y) /100 -----I
This year Sal of 80 is 1.5 X and Sal of 20 remains the same
Avg Sal = (1.5 X + Y)/100 --- II
Unfortunately there is no way calculate II from I. Hence E.
Last year the average salary of the 100 employees of company X was $43,800.What is the average salary of the same 100 employees this year?
1)For 80 of the 100 employees,this year's salary is 15% greater than last year's salary
2)For 20 of the 100 employees,this years salary is same as last years.
IMO C
Deepak,
Whats the problem if x=y=0? Plz elaborate.

If a and b are integers, is b even?
(1) 3a + 4b is even.
(2) 3a + 5b is even.
A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is
sufficient.
D. EACH statement ALONE is sufficient.
E. Statements (1) and (2) TOGETHER are NOT sufficient.
IMO C.
value of a , which we dont know is crucial here.
(1) 3a + 4b is even. -- b has nothing to go to make 3a + 4b even. inSuff
(2) 3a + 5b is even. -- odd a and odd b can suffice and so can even a and even b. InSuff
Taken together
3a + 5b = (3a + 4b) + b
From (1) we know that (3a + 4b) is even. Therefore to make (3a + 4b) + b even, b must be even.
If a and b are integers, is b even?
(1) 3a + 4b is even.
(2) 3a + 5b is even.
A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
C. BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is
sufficient.
D. EACH statement ALONE is sufficient.
E. Statements (1) and (2) TOGETHER are NOT sufficient.
If a and b are integers, is b even?
(1) 3a + 4b is even.
(2) 3a + 5b is even.
A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.
