Algebra is an important topic in the Quantitative Aptitude section of the MBA CET (Common Entrance Test). It tests your ability to solve equations, understand relationships between variables, and apply mathematical concepts to solve problems. Below is a detailed guide to help you prepare for the Algebra section of the MBA CET:
Key Topics in Algebra for MBA CET
1. Linear Equations:
– Solving equations with one or two variables.
– Word problems based on linear equations.
2. Quadratic Equations:
– Standard form: ax^2 + bx + c = 0.
– Finding roots using factorization, quadratic formula, or completing the square.
– Nature of roots (real, imaginary, equal, or distinct).
– Sum and product of roots: α + β = -b / a, α * β = c / a.
3. Inequalities:
– Solving linear and quadratic inequalities.
– Understanding the range of solutions.
4. Sequences and Series:
– Arithmetic Progression (AP):
– nth term: an = a + (n-1) d.
– Sum of first n terms:Â Sn = n / 2 [2a + (n-1)d].
– Geometric Progression (GP):
– nth term: an = ar^(n-1).
– Sum of first n terms: Sn = a (r^n – 1)/ (r – 1) for r ≠1.
– Harmonic Progression (HP):
– Understanding the relationship between AP, GP, and HP.
5. Functions:
– Basics of functions and their properties.
– Domain and range of functions.
6. Logarithms:
– log (ab) = log a + log b.
– log (a/b) = log a – log b.
– log (a^n) = n * log a.
– Solving logarithmic equations.
7. Permutations and Combinations:
– Basics of counting principles.
– Permutations: P (n, r) = n! / (n-r)!
– Combinations: C (n, r) = n! / r! * (n-r)!
8. Probability:
– Basic probability concepts.
– Conditional probability.
– Probability of independent and dependent events.
Preparation Tips for Algebra
1. Understand the Basics: Focus on fundamental concepts like solving equations, inequalities, and progressions.
2. Practice Regularly: Solve various problems to build speed and accuracy.
3. Learn Formulas: Memorize important formulas for quadratic equations, AP, GP, and logarithms.
4. Focus on Word Problems: Many algebra questions are framed as word problems. Practice translating word problems into equations.
5. Use Shortcuts: Learn time-saving tricks for solving equations and finding roots.
6. Solve Previous Year Papers: Practice MBA CET previous year questions to understand the difficulty level and pattern.
7. Take Mock Tests: Simulate exam conditions and improve time management
Important Formulas for Algebra
1. Quadratic Equations:
– Roots: x = {-b ± √ (b^2 – 4ac)} / 2a.
– Sum of roots: α + β = b/a
– Product of roots: α * β = c/a
2. Arithmetic Progression (AP):
– nth term: an = a + (n-1) d.
– Sum of first n terms:Â Sn = n / 2 * [2a + (n-1)d]
3. Geometric Progression (GP):
– nth term: an = ar^(n-1).
– Sum of first n terms: Sn = a (r^n – 1)/ (r – 1) for r ≠1.
4. Logarithms:
– log (ab) = log a + log b.
– Log (a/b) = log a – log b.
– log (a^n) = n * log a.

Exam Strategy
1. Prioritize Easy Questions: Solve straightforward questions first to secure marks quickly.
2. Time Management: Wise time allocation for each question is important. Do not spend too much time on a single problem.
3. Accuracy: Focus on accuracy rather than attempting too many questions incorrectly.
4. Guess Wisely: If unsure, make educated guesses based on elimination or approximation.
By focusing on the above topics, practicing regularly, and taking mock tests, you can master the Algebra section of the MBA CET. Good luck!
