Question

A Group of students collected as many paise from each member of the group as is the number of members . If the total collection amounts to Rs 59.29 , what is the number of members in the group ?

The correct answer is: 77


    Solution
    Hint :- Given  students collected as many paise from each member of the group as is the number of members
    i.e amount paid by each student = no.of students in group.
    Total amount = amount paid by each student * no.of students in the group
    Ans :- 770
    Explanation :-
    Let the no,of students in the group be a
    Given  students collected as many paise from each member of the group as is the number of members
    amount paid by each student = no.of students in group = a.
    The total collection amounts to Rs 59.29 = 59.29 × 100 =  5929 paise
    Total amount = amount paid by each student × no.of students in the group
    5929 equals a squared not stretchy rightwards double arrow a equals square root of 5929
    Apply factorization method to find root.
    5929   =7 × 847
    =7 × 7 × 121
    =7 × 7 × 11 × 11
    equals open parentheses 7 squared space cross times space 11 squared close parentheses equals left parenthesis 77 right parenthesis squared
    We get a = 77.
    Therefore, no.of members in the group is 77.

    In the xy-plane, line  passes through the points (0, 1) and (1, 4). Which of the following is an equation of line  ?

    Note:
    The points on a line in the xy-plane always satisfy the equation of the line. Here, notice that both (0, 1) and (1, 4) satisfy the equation y=3x + 1 . So, an alternate way of doing this problem is to check which equation in the options is satisfied by the given points.
