About this course

Many quantitative aptitude problems rely on a strong understanding of relative values. Master the fundamental concepts of ratio and proportion to unlock faster, more accurate problem-solving skills. This text-only course provides a comprehensive breakdown of ratios, proportions, and their applications. You will move from basic definitions to applying efficient algebraic and non-algebraic techniques necessary for tackling time-constrained tests and practical business scenarios. What you'll learn: * Understand the fundamental definitions of ratios, proportions, and continued proportions. * Master techniques for combining multiple ratios and simplifying complex fractional ratios. * Apply direct and inverse variation principles to problems involving time, speed, distance, and work sharing. * Practice solving common quantitative aptitude scenarios, including mixtures, alliances, and age-based ratio problems. * Learn modern unit-based and algebraic methods to improve calculation speed and accuracy in timed assessments. We start with essential terminology and the rules for manipulating ratios before moving into practical applications. The course emphasizes written exercises designed to reinforce calculation speed and foundational understanding. This course is perfect for absolute beginners in quantitative mathematics or anyone preparing for standardized exams who needs to refresh their foundational skills in ratio and proportion. No prior mathematical knowledge beyond basic arithmetic is required. Start reading today and transform your approach to quantitative problem-solving.
