Answer
Correct Answer: 77
Explanation
Problem restatementA group has n members. Each member contributes n paise (i.e., n/100 rupees). The total collected is ₹59.29. Find n.
Given data
- Total collection = ₹59.29 = 5929 paise.
- Each member pays = n paise; number of members = n.
Concept/ApproachTotal in paise = n (members) × n (paise per member) = n2 paise. Equate to 5929.
Step-by-step calculation n2 = 5929 n = √5929 = 77
Verification/Alternative77 members paying 77 paise each gives 77 × 77 = 5929 paise = ₹59.29.
Common pitfalls
- Treating ₹59.29 directly as 59.29 units instead of converting to paise to match the per-member amount.
