If 30% of X = Y and 40% of Y = Z, then 30% of (X + Y) is: 1] 150% of Z 2] 275% of Z 3] 300% of Z 4] 325% of Z

• GIVEN,
  30% OF X=Y, 40% OF Y=Z
  (30/100)X=Y, (40/100)Y=Z
  (3/10)X=Y, (4/10)Y=Z
  X=(10/3)Y, Y=(10/4)Z
  X=(10/3)(10/4)Z
  X=(25/3)Z
  THEREFORE, (30/100)(X+Y)====?
  =(30/100)((25/3)Z+(10/4)Z)
  =3.25Z
  =325% OF Z

• 325% of Z
  30% of (X+Y)=?
  30% of X = Y
  Y+30% of Y=?
  40% of Y = Z
  130%=325% of Z
