Question

Three of the following four options are alike in a certain way and thus form a group. Which is the one that does NOT belong to that group?

(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g., 13 – Operations on 13 such as adding/subtracting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)

The correct answer is

82 – 8 – 2

Observing the pattern in the given numbers:
- Each of the numbers follows a division or factorization pattern.
Step 1: Checking the relationship in options 2, 3, and 4:
- **164 ÷ 4 = 41** (Option 2 follows the pattern).
- **63 ÷ 3 = 21** (Option 3 follows the pattern).
- **360 ÷ 6 = 60** (Option 4 follows the pattern).
Step 2: Checking Option 1:
- **82 ÷ 2 = 41**, but **8 is not directly related to the pattern** like the others.
Thus, **Option 1: 82 – 8 – 2 does not follow the pattern and is the odd one out**.
Hence, the correct answer is **Option 1**.

    (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 – Operations on 13 such as adding/deleting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)

  4. The following contains two pairs of words which are related to each other in a certain way. Three of the following four word-pairs are alike as these have the same relationship and thus form a group. Which word-pair does NOT belong to that group?
    (The words must be considered as meaningful English words and must not be grouped based on the number of letters/number of consonants/vowels in the word)
