Classification
Classification is a logical reasoning topic where you identify the 'Odd One Out'. In these questions, a set of items is given. All items except one follow a specific rule or share a common feature. Your task is to find that one item that does not belong to the group. This topic is divided into three main categories: Word Classification, Number Classification, and Letter Classification. Word Classification tests your general knowledge.

This concept uses the numerical position of letters to find a pattern. You calculate the difference between consecutive letters in a cluster. For example, in ACE, the gap is +2 (A+2=C, C+2=E).
This concept uses the numerical position of letters to find a pattern. You calculate the difference between consecutive letters in a cluster. For example, in ACE, the gap is +2 (A+2=C, C+2=E). If one cluster has a different gap, it is the odd one out.
This involves finding the odd number based on mathematical rules. Common rules include being a prime number, an even number, or a perfect square. For example, in (13, 17, 19, 21), the number 21 is the odd one.

This refers to grouping words by their meaning or category. Words can be related by profession, habitat, or function. For example, (Ohm, Watt, Ampere, Meter).
