Answer:
(c) 22
Step-by-step explanation:
Non square numbers lie between 11²and 12²
Total numbers between 11² = 121 and 12² = 144
= 122, 123, 124, 125, 126, 127, 128, 129, 130, 131, 132, 133, 134, 135, 136, 137, 138, 139, 140, 141, 142, 143.
= 22 numbers
∵ 11 and 12 both consecutive numbers, so all numbers between their squares are non square numbers.
∴Non square numbers between 11²and 12² = 22
Option (c) is correct.
