Answer 1

John likes 1100. 900.

He likes 400 but not 300; 400 is the square of an integer (20) but 300 is not.

He likes 100 but not 99; 100 is the square of an integer (10) but 99 is not.

He likes 3600 but not 3700; 3600 is the square of an integer (60) but 3700 is not.

900 is the square of an integer (30), but 1000, 1100, and 1200 are not.

Answer 2

400, 3600 and 100 are all square numbers whereas 300, 99 and 3700 aren't. 20x20=400 60x60=3600 10x10=100
