दो रेखीय मॉडल (A(t)=25+6t) और (B(t)=70-3t) कब बराबर होंगे?
When will the two linear models (A(t)=25+6t) and (B(t)=70-3t) be equal?
Explanation opens after your attempt
C. (t=5)
Concept
For equality, set (25+6t=70-3t). This gives (9t=45) and (t=5).
Why this answer is correct
The correct answer is C. (t=5). For equality, set (25+6t=70-3t). This gives (9t=45) and (t=5).
Exam Tip
बराबरी के लिए (25+6t=70-3t) रखें। इससे (9t=45) और (t=5) मिलता है।
