Basic Mathematics

1. Answer any fifteen questions in PART- A. All questions carry equal marks. (15 X 2 =30) 2. Answer all questions, choosing any two sub-divisions each question under Part-B. All questions carry equal marks. (5 X 14 = 70) ( 7 + 7) The Normal equations are = 1(1) + 2(1) + 1(-3) = 0 […]
