## Code

We should create a pattern for solve this type questions

Q. Follow the directions given in the question.

‘R © S’ means that ‘R is greater than S’.

‘R % S’ means that ‘R is not greater than S’

‘R ? S’ means that ‘R is neither smaller than nor equal to S’

‘R * S’ means that ‘R is equal to S’

‘R @ S’ means that ‘R is neither greater than nor equal to S’.

Now based on the above question and assuming them to be true find the correct answer from the conclusions given below.

Statement: A * B, B @ C, C © D, D % E

Conclusion: A) C @ A B) C % A C) E * B D) D © B

1. Only A or B is true.

2. Either A or B and C are true.

3. Only C and D are true

4. Either A or B and C and D are true.

5. Either A or B and D are true.

Answer: To solve this question without any confusion, it is better that you prepare a table first. In the tables mention meaning and symbol in the first column. Now add the symbols and meanings respective to the order given in the question. From the symbols, you can see that R © S is referred to as R is smaller than S. So it will be written as R<S.

 Symbols © % ? * @ value > = > = <

P * S or R is equal to S. Thus, R = S. Also, R © S implies R is greater than S or R > S

P % S means R is not greater than S or R = S

P ? S means that R is neither smaller than nor equal to S or R > S

P @ S and hence R is neither greater than nor equal to S. Thus, P < S.

A = B < C > D = E. Now, the question has become easier and we will only use this table to solve the question. From the question, the statement is: A * B, B @ C, C © D, D % E. This will be decoded into A = B, B < C, C > D, D less than equal to E. On combining the above statements they will be :

Conclusion 1. C @ A ==> C < A. Conclusion 1 is not possible. Because when we combine the statements we found that A is less than C and not the other way around.

Conclusion 2. C % A ==> C = A. This statement is also not possible because A = B and B is less than C, so A < C and it is neither equal to or greater than.

Conclusion 3. E * B ==> E = B. In the combined statements it is given that D = E. Even if we consider that D = E but the other symbols from the statement. And thus this conclusion is also not possible.

Conclusion 4. D © B ==> D > B. C is greater D and B, but there cannot be a direct relationship established between D and B. So this conclusion is also not possible. So the correct answer is the option (5) which is none of this.
