Is ¦x - y¦>¦x - z¦?

(1) ¦y¦>¦z¦

(2) x < 0

in order to conclude that |x-y|>|x-z| or not, we need to know that if quantity inside |x-y| is greater than that inside |x-z| or not. now that is influenced by two factors.

i)the actual quantity of y and z

ii)the sign (+or-) of x,y and z.

this is because we do not know if x,y and z are integers or natural numbers or positive or negative. Genearally if x is common to x-y and x-z the answer depends on if Y > Z or not. say if X is 5 , Y is 3 and Z is 2, the answer could be found from statement 1 itself. But we have to take the negative sign too.

if X is -5 the result wud change. so A alone is insufficient.

if we take the second statement it says, in effect, x is negative. But wat abt Y and Z? so B alone is insufficient.

if we combine these, it is still insufficient as Y and Z may be positive or negative which will alter the final result significantly.

Hence E

hope this helps
