Step-by-step explanation:
, the original scale of the plan was 1:1000
=> 1 mm on map = 1000 mm in original
The plane of a map was photocopied to a reduced size such that a line originally 100mm , measures as 90mm
=> 100 mm on map = 90 mm on photocopied map
=> 1 mm on map = 9/10 mm on photocopied map
9/10 mm on photocopied map = 1000 mm in original
=> 9 mm on photocopied map = 10000 mm in original
=> 1 mm on photocopied map = 10000/9 mm in original
Revised scale = 1 : 10000/9
or 9 : 10000
