How many odd integers are greater than the integer x and less than the integer y?
(1) There are 12 even integers greater than x and less than y.
(2) There are 24 integers greater than x and less than y.
How many odd integers are greater than the integer x and less than the integer y?
(1) There are 12 even integers greater than x and less than y.
(2) There are 24 integers greater than x and less than y.
IMO: B
1.
Lets say x =2 (even)
then y will be either 27 or 28, to have 12 even integers between them.
Lets say x =1 (odd)
then y will be either 26 or 27, to have 12 even integers between them.
Since the number of odd numbers depends on the value of y,
NOT SUFF
2. Definitively gives a value of y.
If x =2, y will be 27, thus 12 odd numbers between them
if x=1, y=26 thus 12 odd numbers between them.
SUFF

FIND odd integrers greater than x but smaller than y
option1:There are 12 even integers greater than x and less than y.
the number of odd integers can not be figured out clearly out here.. it can be 12 or 11..
x = 11
y = 35
odd intergers = 11
Even intergers = 12
x = 12
y = 38
odd intergers = 13
Even intergers = 12
NOT SUFF
option2:There are 24 integers greater than x and less than y
this means equal number of odds and evens, i.e. 12odds and 12 evens..
SUFFICIENT
I would have marked option B ;)
I wud go with option B for the above DS
Q1:
___
If 2 different representatives are to be selected at random from a group of 10 employees and if p is the probability that both representatives selected will be women, is p > 1/2 ?
(1) More than 1/2 of the 10 employees are women.
(2) The probability that both representatives selected will be men is less than 1/10.
Q2:
___
Lines n and p lie in the XY plane.Is the slope of line n less than the slope of line p?
1. Lines n and p intersect at point (5,1)
2. The y intercept of line n is greater than y intercept of line p.
Q1:
___
If 2 different representatives are to be selected at random from a group of 10 employees and if p is the probability that both representatives selected will be women, is p > 1/2 ?
(1) More than 1/2 of the 10 employees are women.
(2) The probability that both representatives selected will be men is less than 1/10.
let A be an event where both representatives selected will be women
option 1: More than 1/2 of the 10 employees are women
take values and check..
for 6 women, the P(A) = 1/3 for 9 women, the P(A) = 4/5 > 1/2
NOT SUFF
option 2: The probability that both representatives selected will be men is less than 1/10.
Does not tell us about the probab when atleast one of the members would be male.. hence NOT SUFF
Combining both options.. no help.. still @ square one..
I would have marked option E..
lemme know the OA plz 😉
Q2:
___
Lines n and p lie in the XY plane.Is the slope of line n less than the slope of line p?
1. Lines n and p intersect at point (5,1)
2. The y intercept of line n is greater than y intercept of line p.
this confused me.. dunno why
question is.. Is the slope of line n less than the slope of line p??.. at this point imagine the XY plane in your mind and imagine how to represent a line with greater slope.. the greater the value of slope, the closer it would be to the vertical line..
option 1:
tells you that the POI is in quad 1.. both X and Y positive quad..
but NOT SUFF
option 2:
tells you that the Y intercept of line n is greater than Y intercept of line p.
means line n hits the Y axis at a point of greater absolute value.. though this might sound like an answer, we still dunno the direction since here we dunno the quad of POI..
hence NOT SUFF
combining both.. we get the answer..
hence answer must be option C..
lemme know the OA plz 😉
@ nuttyvarun
OA s are same are same as your answers! 😃

thanks for confirming man.. hope that helped.. 😉
Tom, Jane, and Sue each purchased a new house. The average (arithmetic mean) price of the three houses was $120,000. What was the median price of the three houses?
(1) The price of Toms house was $110,000.
(2) The price of Janes house was $120,000.

answer must be option C
For finding the median of set of values, one needs to know the values.. here using option 1 and option 2 we can find out the price of Sue's house.. and once we find that out we can find the median value from the set of 3 values..
lemme know the OA 😉

Well.. the option is B! ;)
If one of the 3 values is $120,000 then there could be only options:
- either all three has same values
- or one is less than 120000 and the other one greater
So in any case, median is 120000.

On the number line, the distance between point A and point C is 5 and the distance between point B and point C is 20. Does point C lie between A and B?
1) The distance between point A and point B is 25
2) Point A liest to the left of Point B.
Another one:

1) The distance between point A and point B is 25
2) Point A liest to the left of Point B.
Stat 1-->Dist. b/w A and B is 25...
this can only be possible if C lies b/w A and B.
so suff...
Stat 2-->B can lie anywhere either b/w A and C or outside..
SO not sufficient
hence IMO (A)

1) The distance between point A and point B is 25
2) Point A liest to the left of Point B.
IMO: A
1) AC = 5; AB=25; BC=20
Possible orders are:
B---------C---A (OR) A---C----------B
Either way, C lies between A and B. SUFF
2) possible orders are:
A----C--------B (OR) C----A----------B
So, NOT SUFF
If x not equal to -y, is (x-y)/(x+y)>1 ?
1) x>0
2) y
I feel the answer should be B. When you know Y Any inputs?

yes... answer should be B.
1. If a1, a2, a3, . . . , an, . . . is a sequence such that an=2n for all n 1, is ai greater than aj ?
(1) i is odd and j is even
(2) i2 > j2
2. If S is the sum of the first n positive integers, what is the value of n ?

3. What is the value of t ?
(1) The average (arithmetic mean) of t2 and 8t is -8.
(2) (t^4)^1/2 (^- raised to the power).
Here r some more..
pj02 Saysyes... answer should be B.
But OA is E ! Any idea?
