tanyajoseph wrote:If a > 0, b>0, and c>0, is a(b-c) = 0?
1) b-c = c-b
2) b/c = c/b
Shouldnt the answer be A
Correct me if am wrong.
As 2nd cond says
b^2 = c^2
b^2 - c^2 =0
(b-c)(b+c)= 0
b=c or b=-c
and if b=-c then a(b-c) is not equal to 0

But ans (e) states : x = 1 "AND" z = 0 -- however the explaination given concludes x=1 "OR" z = 0 . Thus to satisfy equation z = xz both the conditions need not to satisfy however ans (e) implies that. I think the only condition that MUST be true is (a) i.e. x = 0 "AND"...
