X,Y,W,Z ARE INTEGER THE EXPRESSION X-Y-Z IS EVEN&Y-W-Z ODD IF X IS EVEN THEN WHICH OF FOLLOWING IS TRUE(a)Y MUST BE ODD(b)Y-Z MUST BE ODD(c)W MUST BE ODD(d)Z MUST BE ODD

• Ans.(c)W must be ODD
  X-Y-Z=even and X even no.
  hence (y-z) must be even because (even -even = even)
  and y-w-z=y-z-w=odd and (y-z) is even so W must be odd because (even - odd=odd)
  hence option (c) is correct

• ans is c.
  X-Y-Z=even
  Y-W-Z=odd
  gn X is even
  =>Y,Z both are either odd or even
  if Y,Z are even then
  W must be Odd
  if Y,Z are odd then
  W must be odd
