If (A(t)=50+7t) and (B(t)=92+4t), at what (t) will (A(t)) be (6) more than (B(t))?यदि (A(t)=50+7t) और (B(t)=92+4t), तो किस (t) पर (A(t)) (B(t)) से (6) अधिक होगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: \(t=16\)\(t=16\)
The condition is \(A(t)=B(t)+6\). So, \(50+7t=92+4t+6\), which gives \(3t=48\) and hence \(t=16\). Therefore, the correct option is \(t=16\). At \(t=14\), the difference is only \(50+98-(92+56)=0\), not 6. Exam tip: translate “6 more than” as \(A=B+6\).शर्त है कि \(A(t)=B(t)+6\)। अतः \(50+7t=92+4t+6\), जिससे \(3t=48\) और \(t=16\) प्राप्त होता है। इसलिए सही विकल्प \(t=16\) है। \(t=14\) पर अंतर केवल \(50+98-(92+56)=0\) होगा, 6 नहीं। परीक्षा टिप: “से 6 अधिक” को हमेशा \(A=B+6\) के रूप में लिखें।
