Answer 2

Answer:

9×10×1=90.Ans.

Step-by-step explanation:

All the no. b/w 100 and 1000 will be 3-digit no.

unit place is fixed .i.e no. just before decimal .i.e hundred place=7

therefore, unit place can have 1 no.

ten's place can have all no. from 0-9

therefore, ten's place can have 10 no.

one's place can have no. from 1-9,

since, a no. starting from 0 will be a 2-digit no.

therefore, one's place can have 9 no.

Ans. 9×10×1=90
