Question

Choose the number that is 5 more than a square number.
21
34
35
65
76

Answer 1

21

Explanation:

this requires practical assumption.

take 9 for example

5 more than 9 means 9 - 5 = 4

4 is a square number

21 = 21 - 5 = 16

16 is a square number

34 = 34 - 5 = 29

29 is not a square number

35 = 35 - 5 = 30

30 is not a square number

65 = 65 - 5 = 60

60 is not a square number

76 = 76 - 5 = 71

71 is not a square number

Answer 2

5 more than a square number would be 21 which is 5 more than 16 (the square of 4)
