Quantitative Aptitude Questions for Banking Exams

• Simple interest formula: Interest = (Principal × Rate × Time) / 100
• A sum doubling in 5 years will become four times in 10 years (assuming simple interest).
• A 20% increase followed by a decrease to return to the original price requires a decrease of approximately 16.67%.
• Compound interest accrues interest on both the principal amount and the accumulated interest from previous periods. Simple interest only accrues on the principal amount.
• Compound interest formula: A = P(1 + r/n)^(nt), where A = accumulated amount, P = principal, r = annual interest rate, n = number of times interest is compounded per year, t = time in years.
• A 25% markup followed by a 10% discount results in a net profit percentage of 12.5%.
• Profit is the difference between revenue and cost. Loss is the difference between cost and revenue. Profit percentage = (Profit / Cost) × 100. Loss percentage = (Loss / Cost) × 100.
• Area and perimeter formulas for different shapes vary by shape.
• Percentages represent a fraction of 100. Proportions show the equality of two ratios.
• Averages: Arithmetic mean = sum of values / number of values; Median = middle value in a sorted list; Mode = most frequent value; Geometric mean = nth root of the product of n values.
• A ratio compares two quantities. A proportion sets two ratios equal to each other.
• The unitary method involves finding the value of one unit and then calculating the value of any number of units.
• Time taken = Distance / Speed = 120 km / 60 km/hr = 2 hours.
• Speed, distance, and time are related by the formula: Distance = Speed × Time.
• Pipe and cistern problems involve calculating the rate at which pipes fill or empty a tank. Solution strategies involve finding the individual rates and combining them to solve the problem under a number of scenarios.

Additional Concepts

• Number System: Includes prime factorization, HCF/GCD, LCM, and different types of numbers (natural, whole, integers, rational, irrational).
• Algebra: Focuses on linear equations, quadratic equations, and simultaneous equations.
• Geometry: Covers basic shapes, angles, coordinate geometry, and mensuration.
• Data Interpretation: Analysis of charts (bar, line, pie), graphs, and drawing conclusions from data.
• Permutations and Combinations: Understanding arrangements, selections, and possibilities.
• Probability: Understanding likelihood and basic probability concepts.
• Time and Work: Problems addressing efficiency, simultaneous work, and combined work scenarios.
• Time, Speed & Distance: Relationships between time, speed, and distance, including scenarios like trains, boats, and cars.
• Ratio & Proportion: Equivalent ratios and problem-solving using ratios and proportions.
