Points to Remember: The area of a triangle with coordinates (x1, y1), (x2, y2), (x3, y3) is given by: 0.5 * |x1(y2 – y3) + x2(y3 – y1) + x3(y1 – y2)| The equation of a line is given. We need to find a point on this line that satisfies the area constraint. Introduction: This … Read more The coordinates of the vertices B and C of a triangle ABC are (1, –2) and (2, 3), respectively. Third vertex A lies on the line 2x + y – 2 = 0. The area of the triangle is 8 square units. Find the coordinates of vertex A.

Points to Remember: Understanding of set theory and probability. Application of Venn diagrams to solve probability problems. Accurate calculation of probabilities. Introduction: This question involves calculating conditional probability using a Venn diagram. We are given the number of students studying different subjects (Maths, French, Business Studies) in a class of 400 students, along with information … Read more There are 400 students in a class. Of these, 270 study Maths, 300 French, and 50 Business Studies. All those who study Maths also study French. 20 study Maths and Business Studies. 35 study French and Business Studies. A student is selected at random. Find the probability that the selected student studies French but neither Maths nor Business Studies. Use a Venn diagram only.

Keywords: Work, days, individual rates, combined work, simultaneous work. Required Approach: Factual and Analytical. This question requires a mathematical approach to solve for an unknown variable (the number of days C takes to complete the work alone). Join Our Telegram Channel Points to Remember: Individual work rates are inversely proportional to the number of days … Read more A and B alone can complete a piece of work in 7 and 14 days, respectively. A and B work together for 2 days, after which C joins them. Now, the work is completed in one day. In how many days can C alone do that work?

Points to Remember: Profit is calculated as Selling Price (SP) – Cost Price (CP). Profit percentage is calculated as (Profit/Cost Price) * 100. The problem involves a direct relationship between cost price and selling price. Introduction: This question is a basic profit and loss problem in mathematics. Profit and loss calculations are fundamental to understanding … Read more If the cost price of 150 shirts is equal to the selling price of 120 shirts, find the profit in percentage.

Points to Remember: This is a word problem requiring the application of averages. We need to solve for the original number of students in the class. The problem involves calculating weighted averages. Introduction: This question is a classic example of a weighted average problem. Weighted averages are used when different groups have different sizes and … Read more The average age of a class was 15 years. When 5 more boys, whose average age was 12 years 6 months were admitted in the class, the average age of the whole class was reduced by 6 months. How many students were there in the class originally?

Points to Remember: The volumes of a cone, hemisphere, and cylinder with the same circular base and height are related through simple formulas. The ratio will be a constant regardless of the specific dimensions of the base and height. Understanding the formulas for the volume of each 3D shape is crucial. Introduction: This question requires … Read more Find the ratio of the volumes of a cone, hemisphere, and cylinder which are made with the same circular base and height.

Points to Remember: Median: The middle value in a dataset when arranged in ascending order. If there’s an even number of data points, the median is the average of the two middle values. Mode: The value that appears most frequently in a dataset. A dataset can have one mode (unimodal), more than one mode (multimodal), … Read more Find the difference between the median and mode of the following data: 25, 33, 72, 65, 29, 60, 30, 54, 32, 53, 42, 52, 42, 51, 42, 48, 45, 47, 46, 33
