Number lying between squares of 10 and 11:
10² = 100
11² = 121
Numbers = (121 - 100) - 1 = 21 - 1 = 20
(The numbers are 101,102,...120)
Number lying between squares of 20 and 21:
20² = 400
21² = 441
Numbers = (441-400) - 1 = 41-1 = 40
(The numbers are 401,402,...440)
10² = 100
11² = 121
Numbers = (121 - 100) - 1 = 21 - 1 = 20
(The numbers are 101,102,...120)
