After the first spray kills 50% of germs, there will be 100 - 50 = <<100-50=50>>50% left.

The second spray kills 25%, but 5% have already been killed by the 50% spray, so it kills 25 - 5 = <<25-5=20>>20%.

After the second spray kills 20% of the remaining germs, there will be 50 - 20 = <<50-20=30>>30% left.
