# Data Suffciency Thread for CAT 2011Quantitative Report

Hi All,
I think there is no Data Sufficiency thread in PG.So Iam creating this Thread dedicated only to Data Sufficiency Questions and Fundas.So why wait Let Start [smiley] [smiley]

when both statements are combined x^1/2 > y ; x^3 > y
this can be multiplied as x should be positive , then equation will be
x^7 > y^4
by combining both the statements we can say x>y .

Sorry i thought in a wrong way .. it can't be proved like that .
No , it cant be solved using both the statements .
it is implied when we combine both the statements that x>0
take 3 case
1=> x=1/16 y=1/7;
2=>x=2 y=7;
3=> x=9 y=7;
by this we can say that data is not sufficient .
P.s : If i am wrong kindly correct me ..

The question can not be answered even by using both the statements together?

Hi friends ,
thank you in advance . :)
Question :
choice 1 : if the question can be solved by using one statmnt and can't be solved by another statement .
choice 2: if the question can be solved by...

my bad...actually i did not solve the root equation..i assumed a value will be obtained...
ya as we r getting two psitive values one greater than 20 and the other less than 20 we can select one only if we know whether 20 is longer side or not.

yes thats wat i wanna say...
that if we apply that square root formula,we will get two roots...
n so for data sufficiency we need distinct ans...
u can use any formula but unless it is mentioned that 20 is longest side or not, we will get 2 values for 3rd side
1 1
which formula will u use to calculate d 3rd side ?
cannot be determined is the answer
both statements required
what is the 3rd side of a triangle?
1) 2 sides are 10m & 20m
2) area is 80sq.m
Data sufficiency
cannot be determined
(n+k)^1/2 > 2( n)^1/2
squaring on both sides
n+k>4n
=> K>3n
statement 1 is sufficient to answer the question?

The question given below is followed by two statements, A and B. Mark the answer using the following instructions:
Mark (a) if the question can be answered by using either statement alone.
Mark (b) if the question can be answered by using one of the statements alone, but cannot be answere...
Q) Is x > y?
(1) x > y
(2) x^3 > y
