Odd Man Out Test-1

The numbers 3, 5, and 9 are all odd, while 4 is the only even number in the group. Therefore:

• Odd numbers: 3, 5, 9
• Even number: 4

Thus, 4 does not belong to the group of odd numbers.

37, 47, 67 and 17 are prime numbers but not 27.

16, 36, 64 and 4 are perfect squares but not 28.

41, 43, 47 and 53 are prime numbers, but not 57.

36 = 6² , 49 = 7² , 64 = 8² , 81 = 9²  and 100 = 10² .

36, 64, 81 and 100 are squares of composite numbers, but 49 is a square of prime number 7.

8 = 2³ , 27 = 3³ , 64 = 4³ , 125 = 5³  and 343 = 7³ .

8, 27, 125 and 343 are cubes of prime numbers but not 64.

343 = 7³ , 121 = 11² , 1331 = 11³ , 2197 = 13³  and 125 = 5³ .

343, 1331, 2197 and 125 are perfect cubes, but not 121.

48, 75, 84 and 57 are divisible by 3 but not 35.

42624, 37573, 74347 and 93339 are palindromes but not 84284.

27, 36, 72 and 45 are divisible by 9, but not 30.
