IBPS Clerk Prelims Model Paper 18

According to the given information
a2x α byz ⇒ a2 x = byz
czx α b2y ⇒ czx = ba2y
and c2z a axy ⇒ c2z = axy
From (ii), we get
c2zx = cb2y
⇒ axyz = cb2y [∴ c2z = from (iii)]
⇒ ax2 = cb2
⇒ a2x2 = acb2
From (i), we get
a2x2 = bxyz
⇒ acb2 = bxyz
[∴ a2x2 = acb2 from (iv)]
⇒ abc = xyz
⇒ abc α xyz
