If (C(t)=310-12t) and (D(t)=70+6t), at what (t) will (C(t)) be (6) less than (D(t))?यदि (C(t)=310-12t) और (D(t)=70+6t), तो किस (t) पर (C(t)) (D(t)) से (6) कम होगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (t=14)(t=14)
The condition is (310-12t=70+6t-6). This gives (246=18t), so (t=\frac{41}{3}), and none of the options is correct.शर्त (310-12t=70+6t-6) है। इससे (246=18t) नहीं बल्कि (t=\frac{41}{3}) मिलता है इसलिए कोई विकल्प सही नहीं है।
