1 CBT-1 Mathematics

What the syllabus lists	What it means and how to prepare
Number system	Number system — basics like integers, fractions and prime numbers; build speed by practising daily.
BODMAS	BODMAS — the correct order of operations (brackets, powers, division, multiplication, addition, subtraction); understand the order rather than memorising it, since one slip changes the answer.
Decimals	Decimals — practise keeping the decimal point in the right place while adding, subtracting, multiplying and dividing.
Fractions	Fractions — numbers written as numerator over denominator; learn to equalise denominators before adding or subtracting.
LCM	LCM — the smallest number that is a multiple of two or more given numbers; used in questions about bells ringing together or events repeating.
HCF	HCF — the largest number that divides two or more given numbers exactly; used in questions about tiling or dividing things equally.
Ratio and Proportion	Ratio and Proportion — comparing two quantities; comes up in mixture, sharing and map-scale type questions.
Percentages	Percentages — a number's share out of a hundred; this is the foundation for profit-loss and interest questions.
Mensuration	Mensuration — finding the area, perimeter and volume of shapes; keep the formula for each shape handy while practising.
Time and Work	Time and Work — how long a job takes alone or together; the easiest method is to work out one day's share of the job first.
Time and Distance	Time and Distance — the relationship between speed, distance and time; practise problems on changing speed and on trains or boats.
Simple and Compound Interest	Simple and Compound Interest — interest earned on money; understand the formula for each and the difference between them clearly.
Profit and Loss	Profit and Loss — comparing cost price with selling price; practise calculating profit or loss percentage.
Algebra	Algebra — forming equations with letters (x, y) to find an unknown value; keep basic identities like (a+b)² and (a-b)² handy.
Geometry and Trigonometry	Geometry and Trigonometry — properties of lines, angles, triangles and basic ratios (sine, cosine, tangent); draw the figure before solving.
Elementary Statistics	Elementary Statistics — basic concepts like mean, median and mode; keep the definitions clear.
Square Root	Square Root — finding the square root of a number; memorising squares of small numbers speeds this up.
Age Calculations	Age Calculations — working out the relationship between the ages of two people, like father and son; solve by forming an equation.
Calendar & Clock	Calendar & Clock — finding the day for a given date, and the angle between clock hands; each has its own method that comes with practice.

Alphabetical and Number Series	Alphabetical and Number Series — finding the hidden pattern in a sequence to give the next letter or number; check both addition-subtraction and multiplication type patterns.
Coding and Decoding	Coding and Decoding — words or letters changed by a fixed rule; first identify the rule, then apply it to find the answer.
Mathematical Operations	Mathematical Operations — symbols like +, −, ×, ÷ are swapped with each other; calculate carefully using the swapped symbols.
Relationships	Relationships — working out family connections between people; drawing a family tree is the most reliable way to solve these.
Syllogism	Syllogism — drawing a valid conclusion from given statements; solve with a Venn diagram, not in your head.
Jumbling	Jumbling — rearranging scrambled letters or words into the correct order; practise spotting familiar letter groups.
Venn Diagram	Venn Diagram — using overlapping circles to show how groups relate to each other; recognising which group fits inside another comes with practice.
Data Interpretation and Sufficiency	Data Interpretation and Sufficiency — reading given data to answer questions, or deciding whether the information provided is enough to answer at all.
Conclusions and Decision Making	Conclusions and Decision Making — reaching the right outcome from a given situation; read each statement carefully and base your answer only on what is written.

- A 6 days
- B 10 days
- C 16 days
- D 8 days
Show answer

D — 8 days

A's one-day work = 1/12, B's one-day work = 1/24. Together = 1/12 + 1/24 = 3/24 = 1/8, so they finish the work in 8 days.

Time and Work
Find the simple interest on ₹5,000 at 6% per annum for 3 years.
- A ₹900
- B ₹600
- C ₹750
- D ₹1,000
Show answer

A — ₹900

Simple Interest = (Principal × Rate × Time)/100 = (5000 × 6 × 3)/100 = ₹900.

Simple and Compound Interest
What is the LCM (Least Common Multiple) of 15 and 20?
- A 40
- B 60
- C 50
- D 75
Show answer

B — 60

15 = 3 × 5, and 20 = 2² × 5. LCM takes the highest power of each prime factor: 2² × 3 × 5 = 60.

LCM
The ratio of two numbers is 5:7. If the smaller number is 35, what is the larger number?
- A 42
- B 45
- C 49
- D 52
Show answer

C — 49

The smaller part (5 units) equals 35, so 1 unit = 35/5 = 7. The larger number (7 units) = 7 × 7 = 49.

Ratio and Proportion
Find the next number in the series: 3, 6, 12, 24, __?
- A 48
- B 36
- C 42
- D 54
Show answer

A — 48

Each number is double the previous one (×2): 3 → 6 → 12 → 24 → 48.

Alphabetical and Number Series
In a certain code, each letter of a word is replaced by the letter that comes 2 places after it in the alphabet (A→C, B→D, and so on). How will the word 'BUS' be coded?
- A CWU
- B DWU
- C DVT
- D DXV
Show answer

B — DWU

Shift each letter 2 places forward: B→D, U→W, S→U. So 'BUS' becomes 'DWU'.

Coding and Decoding
Pointing to a photograph, Rahul said, 'She is the daughter of my grandfather's only son.' If Rahul is male, how is the girl in the photo related to him?
- A Mother
- B Daughter
- C Sister
- D Cousin
Show answer

C — Sister

Rahul's grandfather's only son is Rahul's own father (since he has no brothers). The daughter of Rahul's father is Rahul's sister.

Relationships
A man walks 6 km to the east, then turns and walks 8 km to the north. What is the shortest distance from his starting point?
- A 12 km
- B 14 km
- C 16 km
- D 10 km
Show answer

D — 10 km

The two legs (6 km and 8 km) are at a right angle, so the shortest distance is the hypotenuse: √(6² + 8²) = √(36+64) = √100 = 10 km.
