Erdős problem 124

Let k0k \ne 0 and 3d1<d2<<dr3\leq d_1 < d_2 < \cdots < d_r be integers of gcd equal to 11 such that 1ir1di11.\sum_{1 \le i \le r}\frac 1{d_i - 1} \ge 1. Can all sufficiently large integers be written as a sum of the shape iciai\sum_i c_ia_i where ci{0,1}c_i \in \{0, 1\} and aia_i is divisible by dikd_i ^ k and has only the digits 0,10, 1 when written in base did_i?
