Question

Given signs signify something and on that basis, assume the given statements to be
true and find which of the two conclusions I and II is/are definitely true.
A+B means A is greater than B
A-B means A is equal to B
A=B means A is not equal to B
A*B means A is greater than equal to B
A/B means A is not less than equal to B
Statements
C-D, A*B, D+A
Conclusions
I. B/D
II. C+B​

Answer 1

Only Conclusion 2 is correct.

Answer 2

Only conclusion II follows.

• According to the language given in the question, C is equal to D, A is greater than and equal to B, and D is greater than A.
• Mathematically, C = D, A ≥ B, and D > A.
• According to conclusion I, B should not be less than and equal to D, which is evidently incorrect as A is greater than equal to B and D is even greater than B. This states that B will be less than D. Consequently, the conclusion I does not follow.
• According to conclusion II, C should be greater than B, which is true as C is equal to D, D is greater than A, and A is greater than B. So, D will be greater than B and as C is equal to D, C will also be greater than B. Thus, conclusion II follows.
• As a result, only conclusion II follows.
