Types of Numbers

Natural Numbers: 1, 2, 3, 4, 5... (counting numbers)
Whole Numbers: 0, 1, 2, 3, 4... (natural numbers + zero)
Integers: ...-3, -2, -1, 0, 1, 2, 3... (whole numbers + negatives)
Rational Numbers: Numbers that can be expressed as p/q (e.g., 1/2, 0.75, 3)
Irrational Numbers: Numbers that cannot be expressed as fractions (e.g., π, √2)

🎯 Decimal Comparison Trick

To compare decimals:

Compare digit by digit from left to right
0.5 vs 0.45 → Compare first decimal place: 5 > 4, so 0.5 is larger
0.234 vs 0.24 → Add zeros: 0.234 vs 0.240 → 4 > 3, so 0.24 is larger

1. Which of the following is a rational number?

π √2 0.75 √3

0.75 can be written as 3/4, making it a rational number.

2. Which is the largest: 0.5, 0.45, 0.505, 0.055?

0.45 0.5 0.505 0.055

Comparing: 0.500 vs 0.450 vs 0.505 vs 0.055 → 0.505 is largest.

3. What is the sum of first 5 natural numbers?

10 15 20 25

1 + 2 + 3 + 4 + 5 = 15

4. Which of these is NOT an integer?

-5 0 2.5 100

2.5 is a decimal, not an integer. Integers are whole numbers.

5. Convert 3/4 to decimal:

0.25 0.5 0.75 0.34

3 ÷ 4 = 0.75

🎯 Shortcut: Decimal Comparison Trick

Quick Method:

Write all numbers with same decimal places (add zeros)
Compare left to right, digit by digit
First different digit determines which is larger

Example: Compare 0.6, 0.58, 0.605
→ 0.600 vs 0.580 vs 0.605
→ First decimal: all have same (5 or 6)
→ 0.6 (600) is largest, then 0.605, then 0.58

0.7, 0.707, 0.07, 0.077 0.07, 0.077, 0.7, 0.707 0.077, 0.07, 0.707, 0.7 0.07, 0.7, 0.077, 0.707

Convert: 0.070, 0.077, 0.700, 0.707. Smallest to largest: 0.07, 0.077, 0.7, 0.707

2. What is the value of 1/8 + 3/8?

Enter as decimal

1/8 + 3/8 = 4/8 = 1/2 = 0.5

3. Which is NOT a prime number?

17 19 23 21

21 = 3 × 7, so it's not a prime number (divisible by more than 1 and itself)

4. Convert 7/20 to percentage:

Enter number only (without %)

7/20 = 0.35 = 35%

5. What is the smallest natural number?

1 is the smallest natural number (counting starts from 1)

🌱 Living vs Non-living Things

Living Things (MRS GREN):

Movement – Can move (animals) or grow towards light (plants)
Respiration – Breathe/take in oxygen
Sensitivity – Respond to environment
Growth – Increase in size
Reproduction – Make babies/seeds
Excretion – Remove waste
Nutrition – Need food/water

Examples:
Living: Dog, Tree, Bacteria, Mushroom
Non-living: Rock, Water, Sun, Car
Tricky: Virus → Not fully living (cannot reproduce alone)

⚠️ Hard difficulty - Math + GS Combined - Each correct: 30 XP

1. Find the smallest number that is divisible by both 12 and 15:

This is an LCM problem

LCM of 12 and 15: Multiples of 12: 12,24,36,48,60... Multiples of 15: 15,30,45,60... LCM = 60

2. Which of the following is NOT a characteristic of living things?

Respiration Growth Rusting Reproduction

Rusting is a chemical reaction in non-living things (like iron). All others are characteristics of living things.

3. Three runners complete a lap in 12, 18, and 24 minutes respectively. After how many minutes will they all meet at the starting point?

54 minutes 72 minutes 144 minutes 36 minutes

LCM of 12, 18, 24 = 72 minutes

4. Which organism can make its own food?

Lion Mushroom Green plant Bacteria

Green plants perform photosynthesis and make their own food using sunlight, water and CO2. They are called autotrophs.

5. The product of two numbers is 360 and their HCF is 6. What is their LCM?

Use: HCF × LCM = Product

Formula: HCF × LCM = Product of numbers. So: 6 × LCM = 360, therefore LCM = 360/6 = 60

Percentages + Reasoning Basics + Revision

🔥 Warm-up – Quick Start

1. What is 50% of 100?

2. Find the next number: 2, 4, 6, 8, ?

💎 Core Mission – Understanding Percentages

20 min

What is Percentage?

Percent (%) = Per 100 → Out of 100 parts
50% means 50 out of 100
25% means 25 out of 100
100% means complete/whole

						🎯 Real-Life Example (Money)
						You have ₹100
You spend 20% on food
20% of ₹100 = ₹20
Money left = ₹100 - ₹20 = ₹80

					

Quick Understanding

10% = 10/100 = 0.10
25% = 25/100 = 0.25 = 1/4
50% = 50/100 = 0.50 = 1/2
75% = 75/100 = 0.75 = 3/4

						⚡ Converting Between Forms
						Fraction to %: Multiply by 100 (e.g., 1/4 × 100 = 25%)
% to Fraction: Divide by 100 (e.g., 20% = 20/100 = 1/5)
% to Decimal: Divide by 100 (e.g., 35% = 0.35)

					

⚔️ Practice Arena – Percentages

20 min

1. What is 25% of 200?

25 50 75 100

25% = 25/100 = 1/4. So 1/4 of 200 = 200 ÷ 4 = 50

2. Convert 3/5 to percentage:

30% 50% 60% 35%

3/5 × 100 = (3 × 100)/5 = 300/5 = 60%

3. If 20% of a number is 40, what is the number?

80 200 100 160

If 20% = 40, then 100% = (40 × 100)/20 = 4000/20 = 200

4. What is 10% of 500?

50 100 5 25

10% = 10/100 = 1/10. So 1/10 of 500 = 500 ÷ 10 = 50

5. 0.75 expressed as percentage is:

7.5% 75% 0.75% 750%

0.75 × 100 = 75%

⚡ Reasoning Power-Up – Number Series

5 min

🧠 Number Series Basics

Find the Pattern:

Look at the difference between consecutive numbers
Check if difference is constant (e.g., +2, +3, +5)
Check if ratio is constant (e.g., ×2, ×3)

Example 1: 3, 6, 9, 12, ?
→ Difference: +3 each time
→ Next number: 12 + 3 = 15

Example 2: 2, 4, 8, 16, ?
→ Ratio: ×2 each time
→ Next number: 16 × 2 = 32

⚠️ Hard difficulty - Percentage + Reasoning + Revision - Each correct: 30 XP

1. A student scored 360 marks out of 600. What is his percentage?

50% 60% 65% 70%

Percentage = (Marks obtained / Total marks) × 100 = (360/600) × 100 = 0.6 × 100 = 60%

2. Find the next number: 5, 10, 20, 40, ?

Look for multiplication pattern

Each number is multiplied by 2: 5×2=10, 10×2=20, 20×2=40, 40×2=80

3. Which is larger: 0.6 or 0.58? (Revision from Day 1)

0.6 0.58 Both are equal Cannot determine

0.6 = 0.60 and 0.58. Comparing: 60 > 58, so 0.6 is larger

4. If 30% of a number is 90, find 50% of that number:

First find the complete number, then calculate 50%

If 30% = 90, then 100% = (90×100)/30 = 300. Now 50% of 300 = 300/2 = 150

3. 75% of a number is 300. What is 25% of that number?

75 100 150 200
