Concept
For the symmetric point (3) is the midpoint so the other point is \(2\times3-4.6=1.4\). In symmetry the midpoint is equally distant from both endpoints.
Why this answer is correct
The correct answer is A. (1.4). For the symmetric point (3) is the midpoint so the other point is \(2\times3-4.6=1.4\). In symmetry the midpoint is equally distant from both endpoints.
Exam Tip
सममित बिंदु के लिए (3) मध्य बिंदु होगा इसलिए दूसरा बिंदु \(2\times3-4.6=1.4\) है। सममिति में मध्य बिंदु दोनों सिरों से बराबर दूरी पर होता है।
