NUMBER ANALOGY - TYPES OF ANALOGIES
Analogy means corresponding. In this chapter, we come across 3 types of Analogies namely word, letter, and number. In this type of questions which were based on analogy, a particular relationship is given and another similar relationship has to be identified from the given alternatives. At least 1 or 2 questions are asked from Number Analogy in most of the competitive examinations and some placement papers like TCS Placement papers and Infosys Placement papers and TechMahindra placement papers.
Number Analogy is the one of the important
topics in Verbal Reasoning and Aptitude Questions. We will discuss Word analogy
(or Verbal Analogy) and Letter Analogy of the Verbal Reasoning in next
chapters.
Here we are discussing the various types
of number analogies which were asked in previous placement papers and SBI PO
and SBI clerks examination .And also there models are helpful to you to get
good marks in IBPS PO and clerks examinations and all other competitive
examinations like SSC, CSAT entrance examinations.
