If when k is rounded to the nearest unit, the result is equal to the exact value of n, is it true that n = m?
This means n is the nearest unit, for example if k=12.4, then n=12.
We are looking at if n=m?
(1) When n is rounded to the nearest unit, the result is equal to the exact value of m.
n is already rounded to the nearest unit in itself, that is it is already for example, 12, so m is also 12.
Sufficient
(2) When m is rounded to the nearest unit, the result is equal to the exact value of n.
m could be exactly the value of n. For example 12 each.
Or m could be anything between 11.5 and 12.4 for the value of n as 12.
