Answer: 862

Step-by-step explanation:

Let the third digit of Y be x .

Then , the first digit will be 4x and the second digit will be 3x.

Since , the digits of Y add to 16.

Then we have

$3x+4x+x=16\\\\\Rightarrow\ 8x=16\\\\\Rightarrow\ x=\dfrac{16}{8}=2$

Thus , the third digit of Y = 2

Then the first of Y digit will be $4(2)=8$

The second digit of Y will be $3(2)=6$

Hence, the digits of Y must be 862
