CUET Maths Formulas: The Common University Entrance Test has a variety of subjects and topics. CUET is one of the competitive exams which works as a gateway for admissions in top colleges and universities across the nation. CUET UG has three sections i.e. Language section, general test and domain specific subject. One of its domain specific subjects include Mathematics, which covers the has matopics like Calculus, Algebra, Linear programming, etc.

This article mainly discusses about the main and important formulae of the topics in mathematics. By going through this article, you will be able to strengthen your mathematics preparation for CUET syllabus 2025. A total weightage of questions was 85 in the year 2024 CUET .

Overview of Syllabus and Exam Pattern

The CUET 2025 has been designed to evaluate the knowledge and skills of candidates in various fields. The test can be divided into three separate sections, which are Section I-Language, Section II-Domain Specific Subjects, and Section III-General Test. In the first section, the comprehension of language is tested from English and other languages, according to the choice of the candidate.

Background wave

Section II deals with the domain-specific topic opted by a student, either Mathematics or Physics or Chemistry or Biology, as the case may be, depending upon the stream chosen by the candidate. Section III will therefore test general knowledge, reasoning ability, and problem-solving skills.

Quantitative Aptitude formulae

The CUET Quantitative Aptitude is one of the most essential parts of the CUET test designed to measure a candidate's mathematical skills and problem-solving skills. Topics like arithmetic, algebra, geometry, mensuration, trigonometry, and number systems are very diversified. Below are the crucial formulae with respect to the topics:

Mensuration

Mensuration is one of the prominent topics in CUET QA. In solving many problems on the measurement of areas and volumes and surface areas of different geometric figures, you may have to find the area and the perimeter of any 2D shape - triangles, circles, and quadrilaterals; and the surface area and volume of various 3D solids - cubes, spheres, and cylinders. All the key formulae and their applications need to be well understood to solve them efficiently. Key formulae for mensuration that you are supposed to know for CUET QA are :

Ratio and Percentage

Both ratio and percentage are quite fundamental concepts in the solving of several problems that may evolve in statistics and real life. The ratios, percentages may form part of the problems in CUET QA such as comparing quantities, calculating discounts, profit, and loss, or changes in value over time which each requires considerable use of ratios and percentages. Here are the formulas for ratio and percentage:

Ratio

If the ratio of two quantities isa:b,then their respective values can be written asaxandbx.

The ratio of two quantities isa:b,and their sum isS,then the quantities are:aa+b×Sandba+b×S

Ifa:b=c:d,then the cross multiplication rule applies:ad=bc.

Ifa:b=c:dandb:c=e:f,thena:b:c=ae:be:bf.

Learn about ratios.

Percentage

Percentage of a valueArelative toB=(AB×100)%.

If a value increases byx%:New value = Original value×(1+x100).

If a value decreases byx%:New value = Original value×(1x100).

Successive percentage changes ofx%andy%:Effective change=x+y+xy100.

If a population increases byr%per year, the population afternyears is:P×(1+r100)n

If a population decreases byr%per year, the population afternyears is:P×(1r100)n

Percentage change between two values:Difference in valuesOriginal value×100.

Trigonometry

Trigonometry will comprise 3-5 questions in CUET QA, which will include problems on trigonometric identities, angles, and functions, along with solving triangles and inverse applications of trigonometric functions.

Arithmetic Calculations

Arithmetic calculations form a good quantitative reasoning base for CUET QA. This section tests the ability of doing quick and accurate calculations, involving percentages, ratios, averages, and other formula:

Sum of an Arithmetic Series: Sn=n2(2a+(n1)d)

Nth Term of an Arithmetic Sequence: Tn=a+(n1)d

Sum of First n Natural Numbers: Sn=n(n+1)2

Sum of Squares of First n Natural Numbers: Sn=n(n+1)(2n+1)6

Sum of Cubes of First n Natural Numbers: Sn=(n(n+1)2)2

Arithmetic calculations will be the primary component of most questions in CUET QA, and you would expect to get 4 or 5 questions in this section.

Speed, Distance and Time

This unit covers the relationship between speed, distance, and time, and is also of key importance in solving other practical problems in connection with motion. You will meet questions where constant speed applies, relative speed apply, and problems where you need to find time or distance when given certain conditions. You should use the formula:

Speed=DistanceTime

Distance=Speed×Time

Time=DistanceSpeed

Problems on speed, distance, and time generally form 2-3 questions in the CUET QA exam.

Average

This topic tests your ability to analyze data sets and use the appropriate formula for calculating averages. Simple problems involving the average of test scores, expenses, or prices are common, and you will need to quickly calculate the mean to find solutions.

Average=Sum of all observationsNumber of observations

Weighted Average=i=1n(xiwi)i=1nwi

In these formulas:

xi represents individual observations,

wi represents the weights corresponding to each observation.

The concept of average will constitute around 2 to 3 questions in CUET QA exam. This could include finding the average of a set of numbers, weighted averages, or average speed, average marks, or average income type questions.

Learn more about average.

Compound Interest

Compound interest questions, ask you to calculate interest on the principal and the interest obtained over time by the formula:

Amount (A)=P(1+r100)n

Compound Interest (CI)=AP=P((1+r100)n1)

Where:

A is the amount after interest.

P is the principal amount.

r is the rate of interest per year.

n is the number of years.

Visit: Compound Interest

Simple Interest

Understanding the difference between simple interest and compound interest is vital for CUET QA, especially when dealing with financial calculations. Simple interest problems involve calculating interest on a principal amount over a specified time period using the formula:

Simple Interest (SI)=P×R×T100

Where:

P = Principal amount

R = Rate of interest per annum

T = Time in years

You would expect 2-3 questions under the simple and compound interest. There are problems which talk about computing an interest, amounts or the amount of time it will take for a given amount of principal to grow under these conditions.

Learn more about Simple interest.

Median & Mode

Both median and mode being an important measures of the central tendency in data analysis. In CUET QA, you might be given a set of values, in which you may be asked to find its mean and mode. Below are the formulas for median and mode:

For a grouped frequency distribution:

Mode=L+(f1f0)(2f1f0f2)×h

Where

L = Lower boundary of the modal class

f1 = Frequency of the modal class

f0 = Frequency of the class preceding the modal class

f2 = Frequency of the class succeeding the modal class

h = Class width

Median=L+(N2F)f×h

L = Lower boundary of the median class

N = Total number of observations

F = Cumulative frequency of the class preceding the median class

f = Frequency of the median class

h = Class width

Learn about mode and median.
