  • Question 1
    1 / -0

    Which of the following equation has solution as x = 5?

    Solution

    (1) 4x + 10 = 30
    4x = 20
    x = 5

    (2) 21x + 6 = 30
    21x = 24
    x = 8/7

    (3) 10x + 8 = 32
    10x = 24
    x = 12/5

    (4) 9x + 12 = 48
    9x = 36
    x = 4

     

  • Question 2
    1 / -0

    Riya's uncle is 5 years older than three times the age of Riya. If age of Riya's uncle is 52 years and riya's age is x yrs. Form an equation to find Riya's age.

    Solution

    We know that
    Riya's age = x yrs
    and Riya's Uncle age = 52 yrs
    Age of Riya's uncle = (5 + 3x) years
    According to the question:
    3x + 5 = 52

    The number of mangoes in each small box = x
    Number of small boxes in a large box = 20
    According to the question,
    20x + 7 = 67

    There are 60 candidates who appeared for a test. The highest marks scored by a candidate is 6 times the lowest marks plus 12. The candidate who scored the highest got 126 marks and who scored the lowest is p. Form an equation which will help in calculating the lowest marks.

    Solution

    We know that
    Lowest marks scored by a candidate = p
    Highest marks scored by a candidate = 126
    According to the question,
    6p + 12 = 126

     

  • Question 6
    1 / -0

    Select the INCORRECT statement.

    Solution

    Statement (1) is incorrect because 'y exceeds 4 by 8' can be represented as y - 4 = 8.
    The given statement means y is 8 more than 4.
    So, the equation is: y - 8 = 4
    We can also write it as: y - 4 = 8.

    There are 60 children who all have gathered in a hall. These children have some money with them. Each girl has Rs. 25 and each boy has Rs. 40. If the total amount of money with these 60 children is Rs. 1950 and number of boys is x, then

    (i) the equation formed is _______.
    (ii) the number of boys is _______.
    (iii) the number of girls is _______.
     

      (i) (ii) (iii)
    A. 40x + 25(x - 60) = 1950 40 30
    B. 40x + 25(60 - x) = 1950 30 20
    C. 40x + 25(x - 60) = 1950 40 20
    D. 40x + 25(60 - x) = 1950 30 30
    Solution

    Number of boys = x
    Then, number of girls = 60 - x
    According to the question,
    40x + 25 (60 - x) = 1950
    40x + 1500 – 25x = 1950
    15x = 450
    x = 30
    Number of boys = 30
    So, number of girls = 60 - 30 = 30
