    Subject Name: Math

  • 1. Ages
    If the problem involves a single person, then it is similar to an Integer Problem. Read the problem carefully to determine the relationship between the numbers. This is shown in the examples involving a single person.
  • 2. Algebra
    Algebra is a branch of mathematics that substitutes letters for numbers. Algebra is about finding the unknown or putting real-life variables into equations and then solving them. Algebra can include real and complex numbers, matrices, and vectors.
  • 3. Average
    A calculated "central" value of a set of numbers. To calculate it: add up all the numbers, then divide by how many numbers there are. Example: what is the average of 2, 7 and 9?
  • 4.Boat and Stream
    In water, the direction of a boat along with the stream is called Downstream. The direction of a boat against the stream is called Upstream. The speed of water or stream is denoted by v km/hr.
  • 5. Compound Interest
    Compound interest is interest that accrues on the initial principal and the accumulated interest of a principal deposit, loan, or debt. ... By compounding interest, a principal amount can grow at a faster rate than it would if it only accumulated simple interest, which is only the percentage of the principal amount.
  • 6. Coordinate
    Coordinates. more ... Coordinates are a set of values that show an exact position. On graphs it is common to have a pair of numbers to show where a point is: the first number shows the distance along and the second number shows the distance up or down. Example: the point (12,5) is 12 units along, and 5 units up.
  • 7. Discount
    A discount is a percentage that is subtracted from a number. For example, a 10% discount of $30 is $3 (10% converted to a decimal is .10 and .10 x 30 is 3). So an item that sells for $30 and is being offered at a 10% discount can be bought for $27.
  • 8. Graph
    Definition Of Graph. Statistics: A graph is a picture that represents data in an organized manner. Algebra: A graph is a line or curve drawn on a number line or coordinate plane by joining the points represented by certain ordered pairs.
  • 9. HCF & LCM
    LCM of 10, 15, and 20 is 60. Highest Common Factor (HCF): The largest or greatest factor common to any two or more given natural numbers is termed as HCF of given numbers. Also known as GCD (Greatest Common Divisor).For example, HCF of 4, 6 and 8 is 2.
  • 10. Indices and Surds
    An index (plural: indices) is the power, or exponent, of a number. For example, a3 has an index of 3. A surd is an irrational number that can be expressed with roots, such as 2–√ or 19−−√5 .
  • 11. Mensuration - 2D
    Mensuration is a topic in Geometry which is a branch of mathematics. Mensuration deals with length, area and volume of different kinds of shape- both 2D and 3D.
  • 12. Mensuration - 3D
    Mensuration is a topic in Geometry which is a branch of mathematics. Mensuration deals with length, area and volume of different kinds of shape- both 2D and 3D.
  • 13. Mixed Proportional
    two variables are proportional if there is always a constant ratio between them. ... If one variable is always the product of the other variable and a constant, the two are said to be directly proportional.
  • 14. Mixture (Allegation)
    The rule of alligation enables us to find the ratio in which two or more ingredients at the given price must be mixed to produce a mixture of a desired price. This technique can be applied to any topic like mixtures, profit & loss, simple interest, time & distance, percentage, etc.
  • 15. No. of Factors ! No. of Divisors & Prime Factors
    A prime number can only be divided by 1 or itself, so it cannot be factored any further! Every other whole number can be broken down into prime number factors.
  • 16. Number system
    A number system is a system of writing for expressing numbers. It is the mathematical notation for representing numbers of a given set by using digits or other symbols in a consistent manner. It provides a unique representation to every number and represents the arithmetic and algebraic structure of the figures.
  • 17. Partnership
    Partnership is an important chapter in Quantitative section of IBPS and other banking examination.
  • 18. Percentage
    A percent is a ratio whose second term is 100. Percent means parts per hundred. The word comes from the Latin phrase per centum, which means per hundred. In mathematics, we use the symbol % for percent.
  • 19. Pipes Cistern
    In pipes and water tank we will learn how to solve different types of problems. A water tank or a cistern is connected with two types of pipes to fill and empty it. The pipe which fills the tanks up is called the inlet. The pipe which empties it is called the outlet.
  • 20. Profit and Lose
    Formula: Loss = Cost price (C.P.) – Selling Price (S.P.) Profit or Loss is always calculated on the cost price. Marked price: This is the price marked as the selling price on an article, also known as the listed price.
  • 21. Quadratic Equestion
    we define a quadratic equation as an equation of degree 2, meaning that the highest exponent of this function is 2. The standard form of a quadratic is y = ax^2 + bx + c, where a, b, and c are numbers and a cannot be 0. Examples of quadratic equations include all of these: y = x^2 + 3x + 1.
  • 22. Ratio & Proportional
    two variables are proportional if there is always a constant ratio between them. ... If one variable is always the product of the other variable and a constant, the two are said to be directly proportional.
  • 23. Simple Interest
    Simple interest is a type of interest that is applied to the amount borrowed or invested for the entire duration of the loan, without taking any other factors into account, such as past interest (paid or charged) or any other financial considerations.
  • 24. Speed Time Distance
    An easy way to remember the distance, speed and time equations is to put the letters into a triangle. The triangles will help you remember these 3 rules: Distance = Speed x Time. Time = Distance/Speed
  • 25. Times and Work
    Time and Work Definition. Work is something that is done, for example, pushing a table, making projects etc. Work may be considered as a job. The time taken to complete a given work depends on only one factor that is the number of persons employed to do the work.
  • 26. Trigonometry
    Trigonometry (from Greek trigōnon, "triangle" and metron, "measure") is a branch of mathematics that studies relationships involving lengths and angles of triangles. ... Trigonometry is also the foundation of surveying.
  • 27. Words Problem
    a word problem is a mathematical exercise where significant background information on the problem is presented as text rather than in mathematical notation.
