i think answer cant be determined :|
using st.1 alone,
u = +2 v = -2 and u = -2 v = +2 both satisfy st.1 hence, st.1 alone is not sufficient
using st.2 alone, u = 3 v = 4 and u = 4 v = 3 both satisfy st.2 hence, st.2 alone is not sufficient
using both st. together,
u has to be equal to v in all cases...hence, u is never greater than v

i think answer cant be determined :|
u^2 = v^2 implies u = v or u = -v. so you can't say whethere u>v or not.
statement 2 implies that u and v are both positive. so using both the statements, we can say that u = v.
well....pt well...discussed by slam...over here,,the ans is C...as by using both the statements together-we can reach a common solution,which is not the case if we use either statement alone...regards,dkny.jakhar..P.S. can we have some more questions plz
you all are rite guys!!!!! here is the ans and the explanation The correct choice is (E). 30 can be obtained as a product of two distinct integers in the following manner 1 * 30 (-1) * (-30)2 * 15 (-2) * (-15)3 * 10 (-3) * (-10)5 * 6 (-5) * (-6)Statement 1: From this statement, we know that the value of X is odd. Therefore, X can be one of the following values: 1, -1, 3, -3, 5, -5. So, using the information in statement I we will not be able to conclusively decide the value of X. Hence, statement I alone is not sufficient to answer the question.
Statement 2: From this statement, we know that the value of X > Y. From the given combinations, X can take more than one value. Hence, using the information in statement II, we will not be able to find the value of X.
Combining the two statements, we know that X is odd and that the value of X > Y. The combinations that satisfy both the conditions include X taking the value of -1, -3 and -5.
As the information provided in the two statements independently or together are not sufficient to answer the question, the answer choice is (E).
Guys need your help in the following DS problems. Pls. include explanations!
I) The average (arithmetic mean) weight of four balls is 20 pounds. How many of the balls weigh more than 20 pounds? 1)The median weigh of the balls is 20 pounds 2)None of the balls weighs 20 pounds
II) The high temperatures recorded for each day of a period of 5 consecutive days in February were 34, 30, x, 32, and x degrees Fahrenheit. What was the mode of these temperatures? 1)The median of the five temperatures is equal to the mode 2)The average(arithmetic mean) of the five temperatures is 32
HI there.. ANS-I C, let four balls be A,B,C,&D.; S (A+B+C+D)/4 = 20;
now the median weight of the balls is 20 , so B+C?)/2=20 i.e. B+C=40 and A+D= 40, and as per the second statement no ball weighs 20 pounds hence...from above two eqns we can safely say that by combining two statements...we can get the answer ....
So i think the answer should be C....
ANS-II. my take on the question is B,we can solve the question by using only the seconsd statement... As the average is 32 so we can solve for x. and x =32...so the mode of the would be = 32...
what are the answers.,...
regrds

is 6 a factor of n+3? 1) n is even and divisible by 3 2) n is divisible by 6
A) Statement 1 alone is sufficient but statement 2 alone is not sufficient to answer the question asked. B) Statement 2 alone is sufficient but statement 1 alone is not sufficient to answer the question asked. C) Both statements 1 and 2 together are sufficient to answer the question but neither statement is sufficient alone. D) Each statement alone is sufficient to answer the question. E) Statements 1 and 2 are not sufficient to answer the question asked and additional data is needed to answer the statements
is 6 a factor of n+3? 1) n is even and divisible by 3 2) n is divisible by 6
...................
the answer id "D", each is alone sufficient to answer the question..
explaination:
1) for any multiple of 3 to be divisible by 6, it has to be even.. Since n is divisible by 3 and is even, it has 6 as one of its factors.. now if any multiple of 6 has 3 added to it, it wont be divisible by 6 anymore.. Ergo- n+3 doesnt have 6 as a factor.. So 1 is sufficient..
2) n is divisble by 6, this is proved in the previous statement also.. the rest of the explaination follows same.. hence 2 is also sufficient..
Pls provide answers with explanation: Is x2 y2 a positive number? (1) x y is a positive number. (2) x + y is a positive numbe
1st statement x -y is positive. You have at least 2 options Eg. x=4 y= 1 so x2 is bigger than y2. But you can also have x=4 y= -6 So 4 - (-6) = 10 but x2 (24) is less than y2 (36).
2nd statement x + y is positive. So x cuold be 4 and y 1 or x 4 and y 6 or x could be 4 and y -2 or x could be -2 and y 4.
Using both statements x+y positive and x-y positive means that x is bigger than y. Ans. C.
Pls provide answers with explanations: If x is an integer, what is the value of x? (1) 2(x + 5) (2) 3x > 9
From statement one we have that x is bigger than - 4,5 but we cant know the value of x. From statement two we have that x is less than - 3 but we cant know the value of x. With both statements we can know that x is between -4,5 and - 3 and is an integer, so the value of x is - 4. Ans. C.
