यदि (p>q) और (r>s), तो कौन सा निष्कर्ष हमेशा सत्य है?
If (p>q) and (r>s), which conclusion is always true?
Explanation opens after your attempt
A. (p+r>q+s)
Concept
Adding inequalities in the same direction gives (p+r>q+s), which is always true. Subtraction and multiplication need extra conditions.
Why this answer is correct
The correct answer is A. (p+r>q+s). Adding inequalities in the same direction gives (p+r>q+s), which is always true. Subtraction and multiplication need extra conditions.
Exam Tip
दो सही दिशा वाली असमानताओं को जोड़ने पर (p+r>q+s) हमेशा सत्य है। घटाव और गुणा में अतिरिक्त शर्तें चाहिए।
