This document provides instructions for the 28th Indian National Mathematical Olympiad exam to be held on February 03, 2013. It states that calculators and protractors are not allowed, but rulers and compasses are. It includes 6 multi-part math problems to be solved on separate pages with clear numbering. The problems cover topics like properties of circles touching externally, positive integer solutions to equations, properties of polynomial equations, subsets with integer mean averages, relationships between areas of triangles formed by triangle centers, and inequalities relating positive real numbers.
The document discusses two methods for solving systems of linear equations algebraically: elimination and substitution. For elimination, equations are combined by adding or subtracting to cancel out variables. For substitution, one equation is solved for one variable in terms of the other, and then substituted into the remaining equation to yield a single-variable equation that can be solved. Examples of both methods are provided and explained step-by-step.

The concept of Variables and Constants The Concept of Formulae
Write a Formula Subject of a Formula Find the Value of a Variable
A. Variables and Constants
A variable is a quantity whose value is not fixed.
A constant is a quantity whose value is fixed.
Practice 1
Determine whether each of the following is a variable or constant.
1. The length of the Penang Bridge. (_____________)
2. The mass of new born babies in a hospital. (_____________)
3. The number of sides of a hexagon. (_____________)
4. The monthly consumption of electricity for Ahmad`s family. (_________)
B. Formulae
A formula is an equation which shows the relationship between two or
more variables.
Example: 1 kg of beef costs RM p and 1 kg of fish costs RM q. Puan
Fauziah buys x kg of beef and y kg of fish. The total that
She has to pay is RM t.
Solution:
1 kg of beef = RM p,
x kg = x x RMp = RM px
1 kg of fish = RM q,
y kg = y x RM q = RM qy
Therefore, RM t = RM px + RM qy Ignore the unit
t = px + qy
Maths tip:
Use the same unit or measurement throughout the calculation.
Practice 2: Write a formula based on the given statement or situation.

Given that RM H represents the total
price for m packets of soya bean
drink and n packets of chicken rice.
C. Subject Of A Formula
The subject of a formula is a variable that is expressed in terms of
other variables in the formula.
If a variable is the subject of a formula, then the variable can only lie on
one side (usually left) of an equation and its coefficient must be 1.
Example 1: Given that 2k 2 = 4m 2 + n 2 , express m in terms of k and n .
Solution:
Note:“express m in terms of k and n ” means “express m as the
subject of the formula”.
2k 2 = 4m 2 + n 2
4m 2 + n 2 = 2k 2 Rewrite a = b as b = a
4m2 = 2k2 – n2 Isolate the term 4m2 from the other terms.
