Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (4)(4)
The sum of distances from (-1) and (3) is at least their distance (4). The distance idea is useful for absolute value questions.दो बिंदुओं ( -1 ) और (3) से दूरी का योग कम से कम उनके बीच की दूरी (4) होता है। निरपेक्ष मान में दूरी वाला विचार उपयोगी है।
