Trigonometry

• Basic Ratios: Sine, cosine, and tangent definitions.
• Applications: Solving right triangles and problems involving angles.

Tips for SSC GD Maths Preparation

• Practice Regularly: Solve previous years’ papers and sample tests.
• Time Management: Practice solving problems within a set time.

Ratio and Proportion

• Ratios: Defines the relationship between two quantities as a fraction.
• Proportions: Equates two ratios, establishing a relationship of equality.
• Applications: Solves practical problems involving speed, distance, and time.

Percentages

• Calculating Percentages: Methods for deriving percentage values from given numbers and applying increases or decreases.
• Applications: Used in determining profit and loss, as well as calculating discounts.

Averages

• Mean: Computed by dividing the sum of all values by the total number of values.
• Median: Identifies the middle value in a sorted data set.
• Mode: Represents the most frequently occurring value in a data set.

Time and Work

• Work Calculation: Formula: Work = Rate × Time; crucial for determining task completion.
• Efficiency: Evaluates work accomplished by one or multiple individuals.
• Combined Work: Focus on analyzing collaborative working efforts and total time required.

Simple and Compound Interest
