Size of a partial deck from three remainders

Question

Some cards have been taken out of a standard 5252-card deck. The number left has remainder 11 when divided by 33, remainder 33 when divided by 55, and remainder 33 when divided by 44. How many cards remain?

Short answer

4343. The last two conditions mean the count is 33 more than a multiple of 2020: 3,23,433,23,43 (below 5252). Only 4343 leaves remainder 11 on division by 33.
