Hi dear,
Let the 1st number be a,
2nd =b
3rd=c
4th=d
From your question,
b=3a-4---(1)
c=b/4----(2)
d=5+a----(3)
From equ 1,
a=(b+4)/3---(4)
Put 4 in 3,
d=5+(b+4)/3--(5)
If the sum of a,b,c,d is 115,
Then,

Take the L.c.m and get
23b+92=1380
23b=1380-92
23b=1288
b=56
Put b=56 in equ 2,4,5, and get;
a=20,
c=14,
d=25
So the values of the fisrt,second,third,and fourth numbers are;20,56,14,and 25 respectively.
HOPE THIS HELPS?
Best wishes,
