Odd One Out Type 2

Hint

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

Hint

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

Hint

All other numbers are multiple of 4 except 82.

Hint

All other numbers are prime numbers except 127.

Hint

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

Hint

All other numbers are prime numbers except 27.

Hint

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

Hint

48 = (7)² –1, 15 = (4)² – 1

24 = (5)² – 1, 35 = (6)² – 1

But, 65 = (8)² + 1

Hint

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

Hint

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

Hint

(3)³ + 1 = 28,

(4)³ + 1 = 65,

(5)³ + 1 = 126,

6³ + 1 ≠ 215.

Hint

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

Hint

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

Hint

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

Hint

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

Hint

83 is the only prime number in the group.

Hint

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

Hint

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

Hint

The difference in all the other cases is 12.

Hint

The product in all other cases is 96.

Hint

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.

Hint

It does not have ‘4’ in the middle.

Hint

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

Hint

It is the set of all prime numbers.

Hint

All numbers are prime numbers.

Hint

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