Modern Maths is an essential part of the MBA CET exam, contributing significantly to the Quantitative Aptitude section. Many candidates worry about its complexity, but the truth is, several questions from Modern Maths in MBA CET are relatively easy and scoring. Understanding the key topics and practicing relevant questions can boost your overall MBA CET score.
In this article, we will focus on ten important topics from Modern Maths that frequently appear in the MBA CET exam at an easy difficulty level. We will also provide expected question types and useful shortcuts to help you maximize your marks efficiently.
1. Algebraic Expressions – Finding Expressions
Algebraic expressions form the foundation of algebra in MBA CET. Questions generally involve finding unknown variables using simple equations.
Example Question:
If x + y = 10 and xy = 21, find the value of x^2 + y^2.
Solution:
We use the identity: Substituting values: Thus, the answer is 58.
2. Basic Algebra – Simple Subtraction
Basic algebra in MBA CET involves straightforward subtraction questions, often appearing in number-based problems.
Example Question:
If the sum of two numbers is 95 and their difference is 15, find the numbers.
Solution:
Let the numbers be x and y. Adding both equations: Thus, the numbers are 55 and 40.
3. Summation of Series – Summation of Natural Numbers
Summation problems in MBA CET often test the formula for the sum of the first N natural numbers.
Example Question:
Find the sum of the first 50 natural numbers.
Solution:
Using the formula: Thus, the sum is 1275.
4. AP / GP – Finding Terms and Sum
MBA CET often includes Arithmetic Progression (AP) and Geometric Progression (GP) questions.
Example Question:
The 3rd term of an AP is 12, and the 7th term is 24. Find the first term and common difference.
Solution:
Using the formula: For the 3rd term: For the 7th term: Solving these equations, we get a = 6 and d = 3.
5. Permutations and Combinations – Counting Words Using Given Letters
Permutation and combination questions in MBA CET usually involve arranging or selecting letters.
Example Question:
How many different words can be formed using the letters in the word “MATH”?
Solution:
Since all letters are distinct, the total arrangements: Thus, the answer is 24.
6. Probability – Selecting Non-Green Balls
Probability is frequently tested in MBA CET, with problems involving selection.
Example Question:
A bag contains 5 red, 3 green, and 2 blue balls. What is the probability of selecting a non-green ball?
Solution:
Total balls = 5 + 3 + 2 = 10 Favorable cases (red or blue) = 5 + 2 = 7 Thus, the probability is 7/10.
7. Trigonometry – Heights and Distances
MBA CET includes basic trigonometry questions involving angles of elevation and depression.
Example Question:
A person standing on a tower observes a road at an angle of depression of 30 degrees. If the tower is 50 m high, find the distance of the road from the base of the tower.
Solution:
Using Thus, the distance is 86.6 m.
8. Coordinate Geometry
Coordinate geometry questions in MBA CET test basic distance and midpoint concepts.
Example Question:
Find the distance between points (3, 4) and (7, 1).
Solution:
Using the distance formula: Thus, the answer is 5.
9. Logarithms
MBA CET often includes logarithm-based simplifications.
Example Question:
If log 2 = 0.3010 and log 3 = 0.4771, find log 18.
Solution:
Using logarithmic properties: Thus, the answer is 1.2552.
10. Functions and Graphs
MBA CET tests function graphs and transformations.
Example Question:
If f(x) = x^2 – 4x + 3, find the roots of the function.
Solution:
Factoring: Setting f(x) = 0: So, x = 3, 1.
Conclusion
Modern Maths in MBA CET is not as difficult as it seems. By mastering Algebraic Expressions, AP/GP, Probability, Trigonometry, Coordinate Geometry, and other topics mentioned above, you can easily tackle 5-10 questions in the exam. Regular practice and a strong conceptual understanding will ensure you score well in this section. Keep solving past MBA CET papers and practice mocks to improve your speed and accuracy!
