Mystery number: The number is less than 190000 and greater than 180000.

5000 more than the number has 187000 thousands.

200 less than the number has 4 hundreds.

The answer to it is

180, 000 190, 000

180,000 + 2000 = n = 5000-187, 000

182,000 = n = 182, 000

Or,

180, 000 190,000

n + 5000 = 187, 000 n - 2000 = 180, 000

n = 187, 000 - 5000 n = 180, 000 + 2000

n = 182, 000 n = 182, 000
