Banker’s Discount is a concept in finance related to bill discounting or the valuation of negotiable instruments before maturity. It is often calculated as the Simple Interest on the face value of a bill for the period from the date of discounting until the date of maturity. Banker’s Discount problems frequently appear in various competitive

Pipes and Cisterns problems are a category of aptitude questions that deal with systems of pipes filling and/or emptying a tank or a cistern. These problems typically involve calculating the time taken to fill or empty the tank, either with individual pipes or with a combination of pipes working together. Understanding the concept of rate

Races and Games problems are common in aptitude tests, focusing on scenarios involving competition and strategy, such as athletic contests, board games, or card games. These problems often involve calculating speeds, distances, probabilities, and outcomes based on given conditions or rules. 1. A and B run a race of 200 meters. When A reaches the

Probability is a branch of mathematics concerned with the likelihood of an event’s occurrence. It is quantified as a number between 0 and 1, where 0 indicates impossibility and 1 indicates certainty. The higher the probability of an event, the more likely it is to occur. This concept is widely used in various fields, including

Alligation or Mixture problems involve combining two or more ingredients with different properties (like price, quality, concentration) to get a mixture with a desired property. The principle of alligation helps in finding the ratio in which the ingredients are to be mixed to achieve a specific quality or price in the resulting mixture. These problems

Square Root and Cube Root problems are commonly found in quantitative aptitude tests. They involve finding the square root or cube root of a given number, which are the values that, when squared or cubed, respectively, result in the original number. These concepts are used in various mathematical calculations and real-world applications, like geometry, physics,

Problems on Numbers form a crucial part of quantitative aptitude tests. They involve understanding and applying concepts like divisibility, properties of numbers, arithmetic operations, and number series. These problems require a good grasp of basic mathematical concepts and often involve finding patterns or applying logical reasoning to solve numerical challenges. 1. Find the smallest number

Permutation and Combination are fundamental concepts in probability and counting theory, used in determining the number of ways objects can be arranged (permutation) and chosen (combination). Permutations focus on the arrangement of items where the order is significant, while combinations deal with the selection of items where the order is not important. 1. How many

Area problems in aptitude tests involve calculating the space occupied within a two-dimensional boundary. These problems can include a variety of shapes such as squares, rectangles, circles, triangles, and more complex geometrical figures. Understanding how to calculate the area is essential for various real-life applications in fields like architecture, land development, and interior design. 1.

Clock problems in aptitude tests typically involve understanding the movement of the hour and minute hands and calculating the angles or time intervals between different positions. These problems require a good grasp of how the clock operates, including the speeds of the hands and their positions at different times. 1. At what time between 4
