💡 Analysis & Explanation
Selling Price Analysis ▼
The vendor sells 5 chocolates for ₹1. Therefore, the Selling Price (SP) of 1 chocolate is ₹(1/5).
Profit Margin Integration ▼
The vendor makes a profit of 20% on the cost price. We know that $SP = CP \times (1 + \text{Profit}\% / 100)$. So, $(1/5) = CP \times (1 + 20/100) = CP \times (120/100) = CP \times (6/5)$.
Cost Price Calculation ▼
Solving for CP: $CP = (1/5) \times (5/6) = 1/6$. This means the Cost Price of 1 chocolate is ₹(1/6).
Final Interpretation ▼
Since 1 chocolate costs ₹(1/6), the vendor can buy 6 chocolates for ₹1.
Conclusion ▼
The vendor originally bought 6 chocolates for ₹1.
