Nikita boutgh 30kg wheat at the rate of 8.9 rupees. per kg and 40kg at the rate of 9.9 rupees per kg and sold whole stock at the rate of 9.5 rupees per kg. Find profit or loss?

Answer

To solve the problem step by step, we will calculate the total cost price (CP) of the wheat purchased by Nikita, the total selling price (SP) of the wheat sold, and then determine the profit or loss.

### Step 1: Calculate the Cost Price (CP) of Wheat

1. **Calculate the cost of the first batch of wheat:**
- Quantity = 30 kg
- Rate = 8.9 Rs/kg
- Cost for the first batch = Quantity × Rate = 30 kg × 8.9 Rs/kg = 267 Rs

2. **Calculate the cost of the second batch of wheat:**
- Quantity = 40 kg
- Rate = 9.9 Rs/kg
- Cost for the second batch = Quantity × Rate = 40 kg × 9.9 Rs/kg = 396 Rs

3. **Total Cost Price (CP):**
- Total CP = Cost of first batch + Cost of second batch
- Total CP = 267 Rs + 396 Rs = 663 Rs

### Step 2: Calculate the Selling Price (SP) of Wheat

1. **Total quantity of wheat sold:**
- Total quantity = 30 kg + 40 kg = 70 kg

2. **Selling price per kg:**
- Selling price = 9.5 Rs/kg

3. **Total Selling Price (SP):**
- Total SP = Total quantity × Selling price per kg
- Total SP = 70 kg × 9.5 Rs/kg = 665 Rs

### Step 3: Calculate Profit or Loss

1. **Profit or Loss Calculation:**
- Profit or Loss = Total SP - Total CP
- Profit or Loss = 665 Rs - 663 Rs = 2 Rs

### Conclusion

Nikita made a profit of 2 Rs.
