Erdős Problem #316 — Partitioning Reciprocal Sums Below Two

About 1 year old · traced to

If A⊆NA\subseteq\mathbb{N} is finite, 0∉A0\notin A, 1∉A1\notin A, and

∑n∈A1n<2,\sum_{n\in A}\frac1n<2,

is there always a partition A=A1⊔A2A=A_1\sqcup A_2 into disjoint finite subsets such that

∑n∈Ai1n<1(i=1,2)?\sum_{n\in A_i}\frac1n<1\qquad(i=1,2)?
