only way to solve this question is by using plug in technique
given x-y=61
x=61+y
and value of x+y answer choices
put x+y= 189
we get 61+2y=189
y=64 and x=125
both x& y are perfect cube of 4 & 5 .
so sufficient IMO D

Official Solution:
Barney is forming two large cubes, A and B, with small identical cubes. He used \(x\) small cubes to form cube A and \(y\) small cubes to form cube B. If \(x - y = 61\), then what is the value of \(x + y\)?
A. \(64\)
B. \(125\)
C. \(169\)
D. \(189\)
E. \(216\)
Notice that since large cubes are made from small identical cubes, then both \(x\) and \(y\) must be perfect cubes (a perfect cube is a cube of an integer). So, \(x\) and \(y\) can be: 1, 8, 27, 64, 125, 216, ...
We are given that \(x-y=61\), so \(x\) and \(y\) are 125 and 64, respectively.
Thus, \(x+y=189\).
