If (a_1=1,\ b_1=2,\ c_1=5) and (a_2=2,\ b_2=4,\ c_2=7), what is the correct conclusion?यदि (a_1=1,\ b_1=2,\ c_1=5) और (a_2=2,\ b_2=4,\ c_2=7), तो सही निष्कर्ष क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: Lines are parallelरेखाएँ समांतर हैं
(\frac{a_1}{a_2}=\frac{b_1}{b_2}=\frac{1}{2}), but (\frac{c_1}{c_2}=\frac{5}{7}). Hence the lines are parallel and inconsistent.(\frac{a_1}{a_2}=\frac{b_1}{b_2}=\frac{1}{2}), लेकिन (\frac{c_1}{c_2}=\frac{5}{7})। इसलिए रेखाएँ समांतर और असंगत हैं।
