Guyz a few ques which made me stumble across while preparation:
If q is a multiple of prime numbers, is q a multiple of r?
1) r
2) q = 18. 
A) if statement (1) ALONE is sufficient, but statement (2) alone is not sufficient to answer the question.B) if statement (2) ALONE is sufficient, but statement (1) alone is not sufficient to answer the question.C) if BOTH statements (1) and (2) TOGETHER are sufficient to answer the question asked, but NEITHER statement ALONE is sufficient.D) if EACH statement ALONE is sufficient to answer the question asked.E) if statements (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data specific to the problem are needed.
My OA is C.
Any takers??
i wud tell the correct OA once u come up with answers
Regards
I think the Answer is (E) --> because "r" can take negative values as well and we are not given any information about that.
Does that make sense?

Hi... Plz help me with the following questions:-
Store S sold a total of 90 copies of a certain book during the seven days of last week, and it sold different number of copies on any two of the days. If for the seven days, Store S sold the greatest number of copies on Saturday and the second greatest number of copies on Friday, did store S sell more than 11 copies on Friday?
(1) Last week Store S sold 8 copies of the book on Thursday.
(2) Last week Store S sold 38 copies of the book on Saturday.
------------------------------------------------------
Is (1/p) > ?
(1) p = r
(2) r > 0
-------------------------------------------------------
At a certain store, each notepad costs "x" dollars and each marker costs "y" dollars. If $10 is enough to buy 5 notepads and 3 markets, is $10 enough to buy 4 notepads and 4 markets instead?
(1) Each notepad costs less than $1.
(2) $10 is enough to buy 11 notepads.

for first two i will go with E and C respectively.
can you please confirm
OA's are B, C and E respectively :huh:
Can you plz explain how u arrived at the answer for the 2nd question? Thanks! :confused:

Is (1/p) > ?
(1) p = r
(2) r > 0
lets take first statement
1) p=r =>
1/r >
now lets take r =1 => 1 > 1/3 (true)
now take r =-1 => -1 > -1/3 ( false)
so 1 is not sufficient.......
now lets take second
2) r > 0
but it does give any info about p so we can not say any thing
so not sufficient
now lets take both
in p=r and r> 0
=> 1/r > r/(r^2 + 2) always true
hence C
Hi... Plz help me with the following questions:-

If for the seven days, Store S sold the greatest number of copies on Saturday and the second greatest number of copies on Friday, did store S sell more than 11 copies on Friday?
(1) Last week Store S sold 8 copies of the book on Thursday.
(2) Last week Store S sold 38 copies of the book on Saturday.
The answer is B.
Option 1 does not give enough information about the sales of Friday and Saturday (the two days for which we have some knowledge about the sales activity). The number of books sold on Thurssay has no bearing on Friday's sale.
Option 2 says that the max no of books sold on any day is 38. Now to reach the total of 90 and by satisfying the rule that Friday should be the second max, we get a best case of
S M T W T F S
0 1 2 3 9 37 38
and a worse case of
6 7 8 9 10 12 38
As u can see, Friday's sale cannot be less than 11 and hence B satisfies the requirement.

At a certain store, each notepad costs x dollars and each marker costs y dollars. If $10 is enough to buy 5 notepads and 3 markets, is $10 enough to buy 4 notepads and 4 markets instead?
(1) Each notepad costs less than $1.
(2) $10 is enough to buy 11 notepads.
for the third one:
as per given statement
5x + 3y
is 4x+4y
lets take first statement
as per it x now in equation 3 we are decreasing count of x and increasing count of y.
by reducing x we are saving less than a 1 $ but in this can we buy one more y is not sure ( that depends on price of y and total amount left from $10)
so this is not sufficient
now lets take second statement
as per it
11x x
as we dont have any info about 'y' i.e whether it costs more than x or less than x
we can not say
even if we take both the statements they reveal about 'x' only
so answer will be E (as you confirmed)
..please correct me if m not
i would appreciate if someone could help me understand this DS problem:
Q. if y>=0, what is the value of x?
Option1: x-3| > = y
Option2: |x-3
Also, alongwith the answer, could you plz elaborate on the best approach to tacke inequality problems?
Thanks in advance.

Is the correct answer C, if yes, I'll put my explanations.

Sorry bud....that's not correct

Tarun
The answer is B.
(1) states that the x-3 >=y. The modulus of any number is always positive. So, (1) doesnt help us much.
(2) states that the modulus of x-3| which has to be positive, is less than or equal to a negative number (since y is positive). This cannot happen unless y is 0 and x-3 is 0. Hence x has to be 3. SUFFICIENT!
As for your "best approach" question, there just isnt one. Each question has its own bunch of tricks..
Thanks Vikram. That's the correct answer.
In a problem involving 'mod', do you always consider the value to be positive or do you consider two scenarios: 1) for integer under consideration in the modulus to be 1) positive and 2) negative
hey.. can you plz help me with these questions?.. Thanks a ton!
Six members of a student council of westwood high school were asked to serve on three special committees. Each member of the student council volunteered to serve on atleast one committee. How many students volunteered to serve on all three committees?
1. The activities committee had 3 volunteers. the Homecoming comittee had 2 volunteers and the Welcoming Committee had 4 volunteers.
2. Two students volunteered to serve on both the activities committee and the welcoming committee.

Profits of corporation X over a three-year period averaged 1.2 million dollars. If the corporation had profits in all 3 years, in which of the years were the profits greatest?
1. In the 3rd year, the profits were twice the average of its profits for the first 2 years.
2. Profits were 3 times as great in the 2nd year and 4 times as great in the 3rd year as in the 1st.

1.E
2.B
wat r the OAs?
Hi.. they answers are
1. E
2. D
How did u arrive at 1 (E)? Can anyone provide an explanation for question 2?
1.E
2.B
wat r the OAs?

sorry , i didnt read question carefully......ans is D itself
x= profit in 1st yr
y= profit in 2nd yr
z= profit in 3rd yr
1. z= x+y
we need in which of the years were the profits greatest... it will be in 3rd year as sum of profits of first &second; sums to only third years.... so sufficient
2. y=3x
z=4x
so z will be highest.....so sufficient
For other question i calculated by drawing a venn diagram...i'll post explanation....
Guyz pl help me wid this.....got stuck with relatively easy probs:
1) In a survey of 150 persons, how many were smokers and drinkers?
(I) 80% of the person surveyed were drinkers
(II) 40% of the smokers were drinkers also
I chose OA to be C but its wrong
2) Find the fourth consecutive even number:
(I) The sum of the last two numbers is 30
(II) The sum of the first two numbers is 22
I chose OA B
but its wrong.
pl explain ur method while selecting ur answer....
thanks

In a problem involving 'mod', do you always consider the value to be positive or do you consider two scenarios: 1) for integer under consideration in the modulus to be 1) positive and 2) negative
Generally, inequalities where u hv to find the range of the variable, u need 2 consider both scenarios....
Find the fourth consecutive even number:
(I) The sum of the last two numbers is 30
(II) The sum of the first two numbers is 22
Let no:s be x,x+2,x+4,x+6
1. x+4+x+6=30
so x=10 and 4th term is 16
2. x+x+2=22
so x=10 and 4th term is 16
So ans D
