Denial of Fee Refund – Major Reason of Kota Student Suicides. When it comes to refund, coaching institutes categorically deny refund to student, adopt time passing & mentally harassing tactics or try to persuade the student so as to buy more time so that student remains trapped in their coaching. Students are not aware that as per court order, coaching institutes are bound to refund the remaining fee from date of application for refund. If student is aware, coaching institutes take many months of time so that student is not able to take admission elsewhere or student is not able to take private local tuitions or return the borrowed money. It blocks all options of student. Student feels pressured & takes extreme step. Govt must make strict rules that coaching institute must refund the fee within 15 days in the student's account from date of application for refund and strictly punish the violators of this rule. #kotasuicide #kotasuicidenews #kotasuicidecase #kotasuiciderat

‘Linear Programming’ is a scientific tool to handle optimization problems. Here, we shall learn about some basic concepts of linear programming problems in two variables, their applications, advantages, limitations, formulation and graphical method of solution. 6.1 Linear Inequations . (1) Graph of linear inequations (i) Linear inequation in one variable : etc. are called linear inequations in one variable. Graph of these inequations can be drawn as follows : The graph of and are obtained by dividing xy-plane in two semi-planes by the line (which is parallel to y-axis). Similarly for and . (ii) Linear Inequation in two variables : General form of these inequations are . If any ordered pair satisfies some inequations, then it is said to be a solution of the inequations. The graph of these inequations is given below (for c > 0) : Working rule To draw the graph of an inequation, following procedure is followed : (i) Write the equation in place of a

5.1 Introduction. The limitations of analytical methods have led the engineers and scientists to evolve graphical and numerical methods. The graphical methods, though simple, give results to a low degree of accuracy. Numerical methods can, however, be derived which are more accurate. 5.2 Significant digits and Rounding off of Numbers. (1) Significant digits : The significant digits in a number are determined by the following rules : (i) All non-zero digits in a number are significant. (ii) All zeros between two non-zero digits are significant. (iii) If a number having embedded decimal point ends with a non-zero or a sequences of zeros, then all these zeros are significant digits. (iv) All zeros preceding a non-zero digit are non-significant. Number Number of significant digits 3.0450 5 0.0025 2 102.030070 9 35.9200 6 0.0002050 4 20.00 4 2000 1 (2) Rounding off of numbers : If a number is to be rounded off to n significant digits, then we follow the following rules : (i) Dis
