Is 'b' the median of three numbers a, b and c?
1) a*c=b
2) a+c=b
Confused whether its C or E. Please help. Don't have the OA.

IMO C
Same reasoning as above!

for a = -1 and c = 1/2 will satisfy! a+c = a*cwinny wrote:Is 'b' the median of three numbers a, b and c?

so, numbers -1/2,-1,1/2 then median: -1
also a = 0, b = 0, c = 0, median = 0
Clearly,not sufficient.
Hence E!

Isn't this a Yes/No question. Doesn't it suffice to say that in both cases b is the median, as opposed to asking what is the value of b?n@resh wrote:for a = -1 and c = 1/2 will satisfy! a+c = a*cwinny wrote:Is 'b' the median of three numbers a, b and c?

For -1,-1/2,1/2 - Median would be -1/2(b) and not -1(a)n@resh wrote:for a = -1 and c = 1/2 will satisfy! a+c = a*cwinny wrote:Is 'b' the median of three numbers a, b and c?

Oh, yeap...you are absolutely right @sl750. we no need to worry about the value.sl750 wrote:Isn't this a Yes/No question.

Thanks for enlightening!
Consider the followingThe two statements will be satisfied only a=b=c=0. So answer is C
Statement 1:
а*c=b
0*0=0 b=0 => median
2*2=4 b=4 => not
hence NOT SUFFICIENT
Statement 2:
a+c=b
same cases as (1) apply.
0+0=0 and 2+2=4
hence, NOT SUFFICIENT
Together,
b=a=c=0 hence yes,
b=4 a=c=2 hence, not
Thus,
[spoiler] E BOTH INSUFFICIENT.
