  • Question 1/10
    1 / -0.33

    Select the Venn diagram that best represents the relationship between the following classes.

    Sports, Cricket, Cockroach.

    Solutions

    Given:

    Sports, Cricket, Cockroach.

    Now the Venn diagram will be-

    Sports is a broad category that includes many different types of physical activities and games.

    Cricket is a specific type of sport. Therefore, all cricket is a sport.

    Cockroach is an insect and has no relationship to sports or cricket.

    Thus, the correct answer is (c).

  • Question 2/10
    1 / -0.33

    In the following number-pairs, the second number is obtained by applying certain mathematical operations to the first number. Which numbers should replace X and Y so that the pattern followed by the two numbers on the left side of :: is the same as that on the right side of ::?

    (NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into its constituent digits. E.g. 13 - Operations on 13 such as adding/subtracting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.)

    X : 45 :: 16 : Y

    Solutions

    Given: X : 45 :: 16 : Y

    Logic: 1st Number × 5 - 5 = 2nd Number

    Let's check all the options:

    Option (a) ​X = 14, Y = 85​​​​​

    14 : 45

    14 × 3 + 3 = 42 + 3 = 45

    16 : 85

    16 × 5 + 5 = 80 + 5 = 85

    (Not follows)

    Option (b) X = 14, Y = 75

    14 : 45

    14 × 3 + 3 = 42 + 3 = 45

    16 : 75

    16 × 5 - 5 = 80 - 5 = 75

    (Not follows)

    Option (c) X = 10, Y = 65

    10 : 45

    10 × 5 - 5 = 50 - 5 = 45

    16 : 65

    16 × 4 - 1 = 64 - 1 = 63

    (Not follows)

    Option (d) X = 10, Y = 75

    10 : 45

    10 × 5 - 5 = 50 - 5 = 45

    16 : 75

    16 × 5 - 5 = 80 - 5 = 75

    (Pattern Follow)

    Thus, the correct option is (d) X = 10, Y = 75.

  • Question 3/10
    1 / -0.33

  • Question 4/10
    1 / -0.33

    The sides of a rectangular field are 77 m and 50 m long. Its area is equal to the area of a circular field. What is the perimeter (in m) of the circular field?

    Solutions

    Given:

    Length of the rectangular field = 77 m

    Breadth of the rectangular field = 50 m

    Area of the rectangular field = Area of the circular field

    Formula Used:

    Area of rectangle = Length × Breadth

    Area of circle = πr2

    Perimeter of circle = 2π

    Solution:

    Area of rectangular field = 77 × 50

    Area of rectangular field = 3850 m2

    Area of circular field = 3850 m2

    Perimeter of circular field = 2πr

    Perimeter of circular field = 2 × 227 227 × 35

    => Perimeter of circular field = 2 × 5 × 22

    => Perimeter of circular field = 220 m

    The perimeter of the circular field is 220 m.

  • Question 6/10
    1 / -0.33

    Which of the following structures stores carbohydrates?

    Solutions

    The correct answer is (C) Amyloplast.

    Explanation:

    Amyloplasts are a type of leucoplast responsible for storing carbohydrates in the form of starch. They are found in non-photosynthetic tissues such as roots, tubers, and seeds. Amyloplasts help in starch synthesis and storage, which can later be converted into energy when required by the plant.

    Information Booster:

    • Amyloplasts are abundant in storage organs like potatoes, rice grains, and bananas.
    • They can convert stored starch back into sugar when the plant needs energy.
    • Non-green plastids that do not participate in photosynthesis.
    • Derived from proplastids and can differentiate into other plastid types under specific conditions.

    Additional Knowledge:

    • Aleuroplast

      • Stores proteins instead of carbohydrates.
      • Found in seeds and grains.
    • Elaioplast

      • Stores lipids (oils and fats).
      • Found in seeds and fruits.
    • Chloroplast

      • Contains chlorophyll and is responsible for photosynthesis.
      • Converts light energy into chemical energy (glucose).
