Coded Inequality

• Inequality is one of the most important topics
  from which 3-5 questions are expected in the bank
  exams. Inequalities questions are either asked
  directly or in the coded form both of the types
  are important. Here in this ppt, we are
  discussing the concept of coded inequality

Coded Inequality

• Directions (1-5) The symbols _at_, , , and
  are used in the following questions with the
  meaning as mentioned below-
•  
• P is not smaller than Q is represented by PQ
• P is not greater than Q is represented by P_at_Q
• P is neither greater than nor equal to Q is
  represented by PQ
• P is neither equal to nor smaller than Q is
  represented by PQ
• P is neither smaller than nor greater than Q is
  represented by PQ
•  
• Assuming the given statement to be true, find
  which among the following conclusions is/are
  definitely true?

Coded Inequality

• Q1. Statements M S _at_ Z R N
• Conclusions
• I. M Z     II. R M III.S N
• (a) None is true
  (b) Only I is true
  (c) Only III is true
• (d) Either I or II is true
  (e) All are true
• S1. Ans (d)
• To solve coded inequality based questions, we
  should first convert coded inequality into
  simplified form
• M gt S Z R N
• M Z i.e. M gt Z (false)
• R M i.e. R M (false)
• S N i.e. S gt N (false)

Coded Inequality

• Q2. Statements A B, B M, K M
• Conclusions
• I. K B     II. M _at_ A III. A K
• (a) Only I and III are true
  (b) Only II and III are true
• (c) Only I and II are true
  (d) All are true
  (e) None of these
• S2. Ans (c)
• On converting coded inequality into simplified
  form, we get
• A B M lt K
• K B i.e. K gt B (true)  
• M _at_ A i.e. M A (true)
• A K i.e. A gt K (false)

Coded Inequality

• Q3. Statements R M, M Z, Z _at_ A, Y Z
• Conclusions
• I. R Y     II. Z R    III.Y R
• (a) None is true
  (b) Only II is true
  (c) Only I and II are true
• (d) Only II and III are true
  (e) All are true
• S3. Ans (b)
• On converting coded inequality into simplified
  form, we get
• R M gt Z A
• Y gt Z
• R Y i.e. R gt Y (false)
• Z R i.e. Z lt R (true)  
• Y R i.e. Y gt R (false)

Coded Inequality

• Q4. Statements M S _at_ Z R N
• Conclusions
• I. N Z     II. R M III. S N
• (a) None follows
  (b) Only I is true
  (c) Only III is true
• (d) Either I or II is true
  (e) All are true
• S4. Ans (a)
• On converting coded inequality into simplified
  form, we get
• M gt S Z R N
• N Z i.e. N lt Z (false) 
• R M i.e. R lt M (false)
• S N i.e. S N (false)

• Q5. Statements R M, M Z, Z _at_ A, Y Z
• Conclusions
• I. R Z     II. Z A III.R A
• (a) Only I is true
  (b) Only II is true
  (c) Only I and II are true
• (d) Only II and III are true (e)
  All are true
• S5. Ans (a)
• On converting coded inequality into simplified
  form, we get
• R M gt Z A
• Y gt Z
• R Z i.e. R gt Z (true) 
• Z A i.e. Z lt A (false)
• R A i.e. R A (false)
