The ratios and percentages may form part of the problems in CUET 2026 QA, such as comparing quantities, calculating discounts, profit, and loss, or changes in value over time, each requires considerable use of ratios and percentages. Here are the formulas for ratio and percentage:
If the ratio of two quantities is a:b, then their respective values can be written as ax and bx.
The ratio of two quantities is a:b, and their sum is S, then the quantities are: aa+b×S and ba+b×S
If a:b=c:d, then the cross multiplication rule applies: ad=bc.

Learn about ratios.
Percentage of a value A relative to B=(AB×100)%.
If a value increases by x%: New value = Original value×(1+x100).
If a value decreases by x%: New value = Original value×(1−x100).
Successive percentage changes of x% and y%: Effective change =x+y+xy100.
To calculate x% of a number N: Result = x100×N.
If a population increases by r% per year, the population after n years is: P×(1+r100)n

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.

Memorising mathematical formulas effectively is crucial for scoring well in CUET 2026, as no formula resources are provided during the exam. The motive is to move beyond rote memorisation and develop understanding-based memory hacks that create lasting remembrance of formulas on the actual exam day.
Key Memorisation Tips:
Create formula cards - Write each formula on one side of a card, with the topic/application on the other side for quick review
Link formulas to real applications - Connect abstract formulas to practical problems you can visualise
Practice daily writing - Write out 10-15 essential formulas from memory every morning to strengthen muscle memory
Teach someone else - Explain formulas to friends or family members to reinforce your understanding
Practice under time pressure - Set 2-minute timers to write as many formulas as possible from each chapter

Hello,
Delhi University (DU) offers various engineering courses under its Department of Technology.
Admission to these courses is primarily based on the Joint Entrance Examination (JEE) Main scores. However, some courses may also consider CUET (Common University Entrance Test) scores for admission.
The exact number of seats filled through CUET scores can vary each year and are not publicly disclosed.
Hope it helps !
Admissions for CUET aren't solely based on 2 Non-Med Percentage along with JEE Mains percentile. The eligibility criteria for CUET require students to have scored at least 50% marks in their Class 12th exam for general candidates and 45% for reserved categories.
Additionally, CUET has its own exam pattern, which includes multiple-choice questions divided into three sections:
- Section 1: Language proficiency(English/Hindi/regional languages)
- Section 2: Domain-specific subjects
- Section 3: General Aptitude
It's also important to note that while JEE Mains is a separate entrance exam, some universities may consider both CUET and JEE Mains scores for admission to certain programs. However, the specific admission criteria may vary depending on the university and course.
To confirm the admission criteria for your desired course, I recommend checking the official websites of the participating universities or contacting them directly.
Yes, if the CUET UG application form does not ask for the 10th marksheet upload and only requires a photograph and signature, your application should still be considered valid. Since you are currently appearing for the 12th exams, the system may not require additional documents at this stage. However, double-check the official guidelines or contact CUET support to confirm.
A PG (Postgraduate) degree in Forensic Science, specifically an M.Sc. in Forensic Science, is a two-year program that provides specialized knowledge and skills in the scientific analysis and application of techniques for collecting and analyzing evidence to solve crimes.
