Challenging Question

A school has about 744 students. On a sports meet, the teachers wish to make the students stand in columns, such that the number of students in each column is equal to the number of columns. Find the number of students in each column with the help of techniques used in square root of 74.

 

Solved Examples

 

  1. Example 1 Susan has a list of 74 guests for a party  She has to make the arrangement of chairs, such that the number of rows is equal to the number of chairs in each row.  Find the number of chairs in each row.

    Solution

    Given that Susan has 74 guests.
    Also we have:
    Number of rows = Number of chairs in each row = x
    Total chairs = Number of rows x Number of chairs in each row
    Total chairs = x × x  = x2
    We know that square root of 74 s not a perfect square. Let us try to find the number which is nearest to 74 and is a perfect square.
    The square number greater than 74 is 81
    Hence x2 = 81 = x = 9

  2.  

    Example 2 A group plans for an excursion for its members and decides to collect as much money from each member as the number of members in the group. The total amount collected is $.5476  How many members are there in the group.

    Solution

    Given that the number of members in the group is equal to the amount of money collected from each member.
    Number of member in the group = Amount collected from each member = x
    Total amount collected = $5476
    Number of members × Amount collected from each member = $5476
    x × x = 5476
    x2 = 5476
    x = √5476 = 74
    $74 is collected from each member of the group.
