numerical answers

[queencharlotte]

Two days from closing date and I am still stuck on these,which have numerical answers
1605 GMT (1 digit)
One hears Charles taught us about the Galapagos Islands (2 digits)
Jockey racing out in Northern France (4 digits)
Dramatically replaced by an addingmachine (1 digit)

Please eat sardines or whatever to sharpen those brains, as mine is now past it. I would be truly grateful for any replies

QC can you tell us some of the answers you do have so we can see what we're aiming at. These don't seem to make any sense to me so far.

[Prudie]

Could the first one be 9 (5 past 4??)

Thanks, Prudie. It is the only suggestion I got, so at this stage I will use it. Best wishes
