200. That is to say, 220 is 110% of 200.
400/2 = 200 40/2 = 20 200+20=220
The answer depends on what tables you know. For a very naive user: 220 * 19 = (200 + 20)*(20 - 1) = 200*20 - 200*1 + 20*20 - 20*1 = 4000 - 200 + 400 - 20 = 4180 For more proficient users: 220 * (20 - 1) = 220*20 - 220*1 = 4400 - 220 = 4180 or (200 + 20)*19 = 200*19 + 20*19 = 3800 + 380 = 4180
