Answer 2

Revised  scale = 1 : 10000/9  or  or 9 : 10000

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
