alleryStart learning →Three of these numbers are perfect squares. Which one is not?
- 40
- 25
- 16
- 36
Show answer and solution
Correct answer: A. 40
40 lies between 6 x 6 = 36 and 7 x 7 = 49, so it is not the square of any integer, while 16, 25 and 36 are.

Worked practice questions
Find the number that does not belong: 9, 16, 27, 36
- 27
- 16
- 9
- 36
Show answer and solution
Correct answer: A. 27
27 is 3 x 3 x 3, a cube, and has no integer whose square equals it, whereas 9, 16 and 36 are 3, 4 and 6 squared.
Which of these has no integer whose square equals it?
- 121
- 144
- 169
- 200
Show answer and solution
Correct answer: D. 200
14 x 14 = 196 and 15 x 15 = 225, so 200 is skipped, while 121, 144 and 169 are 11, 12 and 13 squared.
