Can you solve these maths problems? Math is an awesome subject, and not everyone is a fan of a math test or class. The quiz below is designed to help you get familiar with some fundamental math problems.


Questions and Answers
  • 1. 

    What is the square root of 49?

    • A.

      16

    • B.

      45

    • C.

      12

    • D.

      7

    • E.

      10

    Correct Answer
    D. 7
    Explanation
    The square root of a number is the value that, when multiplied by itself, gives the original number. In this case, the square root of 49 is 7 because 7 multiplied by itself equals 49.

    If I have a cirle with a radius of 50yds, what is the diameter?

    • A.

      25yds

    • B.

      314yds

    • C.

      100yds

    Correct Answer
    C. 100yds
    Explanation
    The diameter of a circle is twice the length of its radius. Therefore, if the radius is 50 yards, the diameter would be 100 yards.

    What happens to the area of a rectangle when you double the legth of both sides?

    • A.

      Area is 2x

    • B.

      Area is 4x

    • C.

      Area is 6x

    Correct Answer
    B. Area is 4x
    Explanation
    When you double the length of both sides of a rectangle, you are essentially increasing the dimensions of the rectangle. Since the area of a rectangle is calculated by multiplying its length and width, doubling both sides will result in quadrupling the area. Therefore, the correct answer is "Area is 4x".

      7x10x4

    • E.

      67x4x90

    Correct Answer
    A. 2x4x4.5
    Explanation
    The dimension of a rectangular prism with a volume of 36ft3 is 2x4x4.5.

    If you are selling 15 c-ds to 3 costomers how many c-d does each customer have?

    • A.

      4

    • B.

      8

    • C.

      13

    • D.

      2

    • E.

      5

    Correct Answer
    E. 5
    Explanation
    Each customer receives 5 CDs. This can be determined by dividing the total number of CDs (15) by the number of customers (3). 15 divided by 3 equals 5.

    Pythagoras theorem states:

    • A.

      The product of the square of lengths hypotenuse, base and perpendicular is equal to the sum of the angles.

    • B.

      The square of the hypotenuse is equal to the sum of the base and the perpendicular in a right angled triangle.

    • C.

      The square of the base is equal to the sum of the squares of the other two sides.

    • D.

      The square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.

    Correct Answer
    D. The square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides.
    Explanation
    The answer is correct because it accurately states the Pythagorean theorem, which is a fundamental principle in geometry. The theorem states that in a right-angled triangle, the square of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. This relationship allows for the calculation of unknown side lengths in right-angled triangles and is widely used in various fields of mathematics and physics.

    Sinθ/cosθ =

    • A.

      1

    • B.

      Cotθ

    • C.

      Tanθ

    • D.

      Secθ

    Correct Answer
    C. Tanθ
    Explanation
    The given expression sinθ/cosθ can be simplified using the trigonometric identity for tangent. The identity states that tanθ = sinθ/cosθ. Therefore, the expression sinθ/cosθ is equal to tanθ.

    A grocer sells 100 kg of jaggery partly at 10% profit and partly at 20% profit, gaining 12% on his outlay. How much does he sell at 10% profit ?

    • A.

      80 Kg

    • B.

      88 Kg

    • C.

      75 Kg

    • D.

      None of the above

    Correct Answer
    A. 80 Kg
    Explanation
    The grocer sells 80 kg of jaggery at a 10% profit. This can be determined by setting up a system of equations. Let x represent the amount of jaggery sold at a 10% profit and y represent the amount sold at a 20% profit. We know that x + y = 100 (since the total amount sold is 100 kg) and that 0.10x + 0.20y = 0.12(100) (since the overall profit is 12% of the total outlay). By solving this system of equations, we find that x = 80 and y = 20. Therefore, the grocer sells 80 kg at a 10% profit.
