To solve the logical reasoning questions, you should understand the basic rules for solving such questions. The questions of logical reasoning apply the following rules:
Contra-Positives
Basic IF-THEN Statements
Sample Questions
Sample IF-THEN Scenarios
Only If Statements
Multiple Elements
The OR Separator
Quiz
Contra-Positives
"Atul will eat the apple if Bhanu does not cook". Which statement will be true if you consider this statement.
In these types of logical reasoning question of "If..... then" concept, contra-positive rule is applied. If any "if.... then" statement is given, contra-positive can be formed by taking the apposite of each statement and then interchanging the resulting statements. In other words, the contra-positive negates and switches the parts of the sentence.
In the given statement "Atul will eat the apple if Bhanu does not cook", first write this in the "if....then" form, i.e., "If Bhanu does not cook, Atul will eat the apple". Now apply the contra-positive rule.
The opposite of the first part of the sentence: "If Bhanu does not cook" is "If Bhanu did cook".
The opposite of the second part of the sentence: "Atul will eat the apple" is "Atul did not eat the apple"
Now switch these two parts: "If Atul did not eat the apple, Bhanu did cook". Therefore, this statement is true.
