Answer: (2) 1
Explanation:-
999x + 888y = 1332
divide by 111 from both side,
9x + 8y = 12         ………………………………… (1)
Again,
888x + 999y = 555
divide by 111 from both side,
Then, 8x + 9y = 5                        …………………….. (2)
Solve equation (1) & (2)
x = 4 & y = -3
Then, x + y = 4 + (-3) = 4 – 3 = 1
Hence, the answer is (2) 1.
