Answer:
There are 77 members in the group.
Step-by-step explanation:
1Rs = 100 paise ( Indian Currency Conversion )
Given,
Total amount collected is = Rs 59.29
Now convert Rs 59.29 to paise that is 59.29 × 100 = 5929 paise
Condition :- Paise collection = Total number of members
 Consider any of the above condition as X
 So, X² = 5929
 X = √5929 = 77
Thus, Total number of members in the group is 77 [ Option C ]
Hope this helps you.
