Best answer
C.
The given numbers are in octal representation. Digits range from $0$ to $7$.
$Y=7526-4364$

$\;\;\;7526$
$-4364$
   _______
  $\;3142$

steps : 1. $(6-4) =2$
            2. $(2-6)$ , borrow a $8$. Now $(8+2-6)=4$
            3. $(5-1-3) = 1  $        (Subtracted by 1 because ONE $8$ was borrowed)
            4.$ (7-4) = 3$
