Answer: £1.50.

The 50th percentile (median) is calculated as the average of the two middle values when the data is ordered. For the given EPS values (-£0.50, £0.50, £2.50, £5.50), the two middle values are £0.50 and £2.50. The median is therefore (£0.50 + £2.50) / 2 = £1.50. This aligns with the 50th percentile calculation using linear interpolation, where the position Ly = (4 + 1)(50/100) = 2.5, and the interpolated value is £0.50 + (£2.50 - £0.50) * (2.5 - 2) = £1.50. Option B (£2.00) is incorrect as it represents the average EPS, not the median. Option C (£2.50) is incorrect as it is one of the middle values but not the median itself.
