यदि (u<v) और (r<s) है, तो कौन सा कथन हमेशा सही है?
If (u<v) and (r<s), which statement is always correct?
Explanation opens after your attempt
A. (u+r<v+s)
Concept
Adding inequalities in the same direction gives (u+r<v+s). Subtraction, multiplication, and division need extra sign conditions.
Why this answer is correct
The correct answer is A. (u+r<v+s). Adding inequalities in the same direction gives (u+r<v+s). Subtraction, multiplication, and division need extra sign conditions.
Exam Tip
एक ही दिशा की असमानताओं को जोड़ने से (u+r<v+s) मिलता है। घटाव, गुणा और भाग के लिए अतिरिक्त चिन्ह शर्तें चाहिए।
