Q 21.8: Sheet of lead 5 mm thick reducing the intensity of beam of gamma rays by a factor 0.4. Find the half value thickness of lead sheet which will reduce the intensity to half of its initial value.

Where has 0.5I° came from in the question?
The value is mentioned in the question. The intensity of initial value (Io) reduced to half of its initial value which will be (1/2 Io). When we simplify the value, it will be 0.5 Io.
