Let one part be x and another part will be 84-x.
According to our question 1/3(x)=1/4(84-x)
X/3=84-x/4
By cross multiplication,
4x=3(84-x)
X=252

Solution:
Let the 1st number is =X
And , the 2nd number is= Y
According to question,
X+Y=84
=> X=84-Y -------------------- (1)
AND,
1/3×X=1/4×Y
=>X/3= Y/4
=>3Y =4X
=>3Y= 4(84-Y) {from equation (1)
=>3Y= 336 -4Y
=>3Y+4Y =336
=>7Y=336
=>Y=48
Now, putting the value of Y in the equation(1) we get-
X=84-Y
=>X=84-48
=>X=36
Therefore,
The 1st number will be=36
AND the 2nd number will be =48
