HEYA!!
---------

Let the Numbers be 12 x and 3 x respectively.


According to the given question:

12x + 3x = 385

15 x = 385

x = 385 / 15

x = 25


Hence the numbers are

25 ( 12 ) = 300

25 ( 3 ) = 75

Answer 2

Let the common ratio ---x
Then ,
No.1=12x
No.2= 3x

according to question

12x+3x = 385
15x=385
x=385÷15
x=25.6


therefore,
N0.1= 12x25.6
=307.2

No.2== 3x25.6
= 76.8



and now you can verify it ,::::::::


U got 384
which is approximately true
