Basic Concepts of Classification
- To ‘classify’ means to assign some particular characteristic to the various member/part of a group and identify them on the basis of those particular characteristics only.
- Classification questions aim to test the skills of a candidate in determining the features of various things and candidate has to answer which one is odd-one from the group of 4 options. The odd-one option shouldn’t possess the skill which must be common among the other four options.
- Such questions are really scoring as they require minimum calculations (if verbal). So, let’s understand how to solve various types of ‘Classification’ questions.
- All we have to do is identify the common feature in the 3 option. There can be various types of patterns which can be found in Classification questions. Some of those patterns are:
This common feature must be unique, ascertainable, non-imaginary and must not be present in odd-one option.
Different Types of Questions asked in UGC NET Exam
1. Finding the Odd-Word: In such questions, four ‘meaningful’ words are given. These words can be found in the dictionary. Apart from that, these have a similar feature, based on that we’re supposed to find the odd-word. For example:
Solution: Here, we can see that all except Morbid are synonymous to each other as they all mean ‘falsehood’ while ‘morbid’ means ‘diseased’. So, here we should have a good vocabulary to solve such questions.
2. Finding the odd-pair of words: In such questions, four options are given. Each option has a pair of words (that can be found in the dictionary & hence meaningful). Each three pair depicts a relationship among each other and this relationship is common in all the four pairs but can’t be found in 4th odd-one pair. We’re supposed to find that odd-pair which doesn’t possess that common relationship. For example,
a) Lion: Roar
b) Snake: Hiss
c) Frog: Bleat
d) Bees: hum
Solution: In all the pairs, the second word is the sound made by the animal which is also the first word. But in the pair of frog: bleat, bleat is the sound made by sheep not frogs.
3. Finding the odd number: In such questions, four numbers are given. Each of the 3 numbers have common features like they are prime numbers or odd numbers or all divisible by ‘7’ while the 4th number isn’t so we have to identify that odd-number which doesn’t have the feature the other four numbers have. For example:
Solution: Here, all the numbers except 399 are of the form (Square + 1) like 257 ⇒ 162 + 1 But 399 ⇒ 398 + 1 ⇒ 398 isn’t the square of any number.
4. Finding the odd-pair of numbers: In such questions, four options are given. Each option has a pair of numbers. Each four pair depicts a relationship among each other and this relationship is common in all the three pairs but can’t be found in 4th odd-one pair. We’re supposed to find that odd-pair which doesn’t possess that common relationship. For example:
a) 140 - 45
b) 110 – 35
c) 100 – 30
d) 80 – 25
Solution: The pattern seen here is (first number – 5) ÷3= Second number. like 140 – 45 ⇒ (140 – 5) ÷ 3 = 45 But 100 – 30 ⇒ (100 – 5) ÷ 3 ≠ 30
5. Finding the odd letters: In such types of questions, four options contain a random group of letters. These random groups of letters have the common pattern and this pattern is common in all the three options but can’t be found in 4th odd-one. We’re supposed to find that odd-one which doesn’t possess that common pattern. For example:
Solution: All except JFHG contain consecutive alphabets in random order.
