Coded inequality SHORTCUTS FOR REASONING ABILITY
Few points to remember
A) Similar points between two variable and common variable in middle .Conclusion is similar signs .
1)A>=B, B>= C
conclusion: A>=C
2)A<=B,B<=C conclusion: A<=C 3) A>B, B>C
conclusion: A>C
4)A=and > and <=and < prevails then conclusion is >and < 6) A>=B , B>C
conclusion : A> C
7) A<=B, B< C C) If the conclusion we get >= or <= signs and in option we have two choices >and
= signs or < and = between two variables then conclusion will be either choice follow Ex- A>=B , B>= C A<=B, B<=C 1)AC, 2) A=C Our answer is either 1 or 2 D) We can't combine two variables with common variable in middle having sign >= and <=or > and < for example 1)A>=B, B<=C no conclusion between A and C 2) A>B , B < C no conclusion between A and C E) At least if we don't get any conclusions yhen we check for complementary pair. So there are two complementary pair 1) >= and < 2) <=and >
Ex: 1)A>=B, B <=C conclusion: a) A >= C
b) A <=C d) A >C
Ans: Either a or b
Either c or d
E) If any new alphabet is compared in the conclusion part ,and if it is not used in the question part then it can't have a definite conclusion .It will have complementary pair
Ex- A >=B, B>=C
option 1) T > C
2)T<=C 3) T>= C
4) T
conclusion : either 1 or 2 and either 3 or 4
P @Q means P is either greater than or equal to Q
P+ Q means P is either smaller than or equal to Q
P%Q means P is greater than Q
PX Q means P is smaller than Q
P$ Q means P is neither greater than nor smaller than Q
Now in each of the following questions assuming the given statement to be true ,find which of the two conditions I and II given below them is /are definately true ? Give answer.
a) If only conclusion I is true
b) If only conclusion II is true
c) If either I or II is true
d) If neither I or II is true
e) If both I and II is true
1) Statements : M @R , R%T , T$ K
