If y/(x - z) = (y + x)/z = x/y then find x : y : z ? Choose the correct choice:
A) 1 : 2 : 3 B) 3 : 2 : 1 C) 4 : 2 : 3 D) 2 : 4 : 7 E) none of these
Given, y/(x - z) = (y + x)/z   yz = xy + x2- yz - xz .. (1)   Also (x/y) = (y/(x - z)) =&gt; x2 - xz = y2 .. (2)   Using (1) and (2), we get yz = xy - yz + y2   2yz = xy + y2   2z = x + y   Only option (c) satisfies the equation   ANSWER:4 : 2 : 3
