= White White White

What Numbers are Blue, Red, White ?

Answer 1

Let's assume that last digit is 1..Then 1+1+1 =3. Which is not 1. Thus it cannot be 1. Same for 2, 3, 4, 6, 7, 8, 9. So it leaves us with 0 and 5 being the only number where 3 times that number comes as that same number in last unit place. 

Thus, white white white can either be 000 or 555. But since white white white is sum of 3 numbers, it cannot be 000. Thus white white white = 555. 

Now, 555/3 = 185. Thus blue red white = 185. 
which gives us, 
blue = 1
red = 8
white = 5

Answer 2

Answer:

185+185+185=555

Explanation:

Blue as X, Red as Y, White as Z

XYZ+XYZ+XYZ=ZZZ

Take ZZZ:

000,111,222.......999

Divide ZZZ by 3 we get XYZ

(i.e.,)XYZ=ZZZ/3

000/3=000(not possible because we get x=y=z all are different digits)

111/3=037

222/3=074

333/3=111

444/3=148

555/3=185

666/3=222

777/3=259

888/3=296

999/3=333

Take Z values same in XYZ and ZZZ

we have only one solution

555/3=185
