Consider a software program that is artificially seeded with $$100$$ faults. While testing this program, $$159$$ faults are detected, out of which $$75$$ faults are from those artificially seeded faults. Assuming that both real and seeded faults are of same nature and have same distribution, the estimated number of undetected real faults is ____________.
