In general, we can say that there are 2n nonperfect square numbers between the squares of the numbers n and (n + 1). 

(i) The number of non-square numbers that lie between the square of 100 and 101 will be = 2(100)  = 200.

(ii) The number of non-square numbers that lie between the square of 90 and 91 will be = 2(90) = 180.

(iii) The number of non-square numbers that lie between the square of 1000 and 1001 will be = 2(1000) = 2000.
