  • Question 2/10
    1 / -0.33

    Which two signs and numbers should be interchanged to make the following equation correct?

    16 Χ18+2-14÷3=38

    Solutions

    By checking option A:

    16 Χ18+2-14÷3=38

    After interchanging signs:

    16 Χ14-2+18÷3=38

    On solving,

    224-2+6=38

    228=38

    So, its not correct.

    By checking option B:

    16 Χ18+2-14÷3=38

    After interchanging signs:

    14 -18+2 Χ 16÷3=38

    Here 16 is not perfectly divisible by 3, so it will result in decimal.

    So, its not correct.

    By checking option C:

    16 Χ18+2-14÷3=38

    After interchanging signs:

    16 +14 Χ 2-18÷3=38

    On solving,

    16+28-6=38

    38=38

    So, its correct.

    As we found the correct answer, so we do not need to check more options.

    Hence, option C is the correct answer.

    Solutions

    Total number of person in the age group of 20 – 50 years of :

    A =

    B =

  • Question 5/10
    1 / -0.33

    What is the value of  ?                     
    Solutions

    = 6 + 2√3 – 8 – 2√3

    = – 2

  • Question 6/10
    1 / -0.33

    If x + y = 3, x3 + y3 = 7, then find the value of 18xy.
    Solutions

    Given, x + y = 3 and x3 + y3 = 7
    We know that, (x + y)3 = x3 + y3 + 3xy(x + y)

    ⇒ 27 = 7 + 9xy

    ⇒ xy = 20/9

    So, 18xy = 18×(20/9) = 40

    • The uppermost layer over the earth’s surface is called the crust.

    • It is the thinnest of all the layers. It is about 35 km on the continental masses and only 5 km on the ocean floors.
