Odd One Out Type 2

All others are divisible by 7 where as 65 is not divisible by 7.

All others are not a cube number but 27 is a cube number.

All other numbers are multiple of 4 except 82.

All other numbers are prime numbers except 127.

All other numbers are the square of other number except 8.

All other numbers are prime numbers except 27.

All other numbers are prime numbers except 9 while 9 is a composite number.

48 = (7)² –1, 15 = (4)² – 1

24 = (5)² – 1, 35 = (6)² – 1

But, 65 = (8)² + 1

All others are not divisible by 3 whereas 345 is divisible by 3.

In all the rest numbers, the third digit is the product of first and second digit.

(3)³ + 1 = 28,

(4)³ + 1 = 65,

(5)³ + 1 = 126,

6³ + 1 ≠ 215.

In all the rest pairs, the difference is divisible by 3.

In all other numbers, the sum of the digits is 17.

In all the rest groups there is no common factor of the two numbers.

In all other pairs, one number is the square of the other.

83 is the only prime number in the group.

In all other groups, the first number is obtained by adding 2 to the product of the second and the third numbers.

(9 – 7)² = 4, (13 – 7)² = 36, (11 – 7)² = 16, but (9 – 5)² ≠ 25.

The difference in all the other cases is 12.

The product in all other cases is 96.

The first two are to be added and the third is to subtracted to give a constant no. 6 viz. 5 + 4 – 3 = 6, 8 + 3 – 5 = 6, etc. but 6 + 5 – 4 ≠ 6.

It does not have ‘4’ in the middle.

The total no. of digits is seven, others are six.

It is the set of all prime numbers.

All numbers are prime numbers.

The sum of all numbers in each set is 100 except (b) ≠ 100 .
