    A group of students decided to collect as many paise from each member of the group as is the number of members. If the total collection amounts to Rs.59.29, the number of members in the group is ____.

    A)  57                              

    B)         67      

    C)         77                              

    D)         87

    Correct Answer: C

    Solution :

    Let the number of members be x. Then, the amount received from each member = x paise. Now, total collection \[={{x}^{2}}\text{ }paise\] \[\Rightarrow (59.29\times 100)\text{ paise }=\text{ }{{x}^{2}}\text{ paise}\] \[\Rightarrow 5929={{x}^{2}}\Rightarrow x=77\] So, number of members = 77
