Number Classification - Choosing The Odd Numeral
Number Classification - Choosing The Odd Numeral
In these type of questions, certain numbers are given, out of which all except one share some common property and hence are alike. From the given numbers, one number is different and this number is odd among them and hence is chosen to be the answer.
Example 1 : Find the odd one out of these 51, 144, 64, 121, 256
(a) 51 (b) 144 (c) 64 (d) 121 (e) 256
Answer : (a)
Explanation : as we analyse the items in the group we see that
144 is square of 12,
64 is square of 8,
121 is square of 11,
256 is square of 16
But 51 is not a square of any number hence is the odd one in the group.
Example 2 : Find the odd one out of these 38, 57, 76, 95, 118.
(a) 38 (b) 76 (c) 118 (d) 57
Answer (c)
Explanation : In the given numbers every term is multiple of 19, but only 118 is not multiple of 19.
19X2 = 38
19X3 = 57
19X4 = 76
19X5 = 95
19X6 = 114....soon
So, the odd one is 118.
Example 3 : Identify the odd one out of these 2384, 1592, 3756, 4298, 3629
(a) 2384 (b) 1592 (c) 3756 (d) 4298 (e) 3629
Answer : (e)
Explanation : When we analyse the items we see that
In 2384 we see that the last digit that is 4 is double the first digit 2
In 1592 we see that the last digit that is 2 is double the first digit 1
In 3756 we see that the last digit that is 6 is double the first digit 3
In 4298 we see that the last digit that is 8 is double the first digit 4
But in 3629 we see that the last digit that is 9 is not the double the first digit 3 Hence this number is the odd element.
Example 4 : Identify the odd one out of these 144, 196, 216 ,256, 289.
(a) 144 (b) 196 (c) 216 (d) 256 (e) None of these
Answer : (c)
Explanation : In the given terms every number is the square of number except 216.
But,
So, the odd one is 216.
Example 5 : Identify the odd one out of these 7, 15, 31, 57
(a) 7 (b) 15 (c) 31 (d) 57
Answer : (d)
Explanation : when we analyse the items we see that
7 can be obtained from the formula
15 can be obtained from the formula
31 can be obtained from the formula
But 57 can not be obtained from this formula or we can say can not be expressed as a power of 2. Hence,57 is the odd one in the group.
Example 6 : Identify the odd one out of these 1728, 2197, 1024, 2744, 3375
(a) 1728 (b) 2197 (c) 1024 (d) 2744
Answer : (c)
Explanation : In the given terms, all are the cubes of numbers except 1024.
But
So, odd one is 1024.
