Surely you don't need to lift it, just tip up one side. I reckon that should halve the effort, so 150 (ish) some lifting, some pushing the side. Seems plausible to me
I wouldn't call that average! :|

You wouldnt get sufficient number of people spread around to be able to get an effective grip enough to lift it.
100 people required apparently:

And where would that 100 people each get a hold to gain maximum lift.
Remember watching a video from Japan I think of a train carriage being lifted to release person trapped underneath. The technique used was to have some lifting while others pushed against the side of the carriage causing it to tilt.
Using an average of 80kg per person = 6 x 80 = 480kg
Weight of double decker = 10 tonnes or 10,000kg
Total weight = 10,480kg
Say the average person can lift 50kg and due to the awkwardness of the object.
I'd say 210 people but how they'd all manage to get a grip at the same time would be a feat.
