A man bought 20 cows in Rs 200000. If the average cost of 12 cows is Rs12500, then what will be the average cost of remaining cows?

Answer

To solve the problem step by step, let's break it down:

### Step 1: Calculate the total cost of 20 cows.
The man bought 20 cows for Rs. 200,000.

**Total Cost of 20 Cows = Rs. 200,000**

### Step 2: Calculate the total cost of 12 cows.
The average cost of 12 cows is given as Rs. 12,500.

**Total Cost of 12 Cows = Average Cost × Number of Cows**
\[ \text{Total Cost of 12 Cows} = 12,500 \times 12 = 150,000 \]

### Step 3: Calculate the total cost of the remaining cows.
To find the total cost of the remaining cows, subtract the total cost of the 12 cows from the total cost of all 20 cows.

**Total Cost of Remaining Cows = Total Cost of 20 Cows - Total Cost of 12 Cows**
\[ \text{Total Cost of Remaining Cows} = 200,000 - 150,000 = 50,000 \]

### Step 4: Calculate the average cost of the remaining cows.
The number of remaining cows is \(20 - 12 = 8\).

**Average Cost of Remaining Cows = Total Cost of Remaining Cows ÷ Number of Remaining Cows**
\[ \text{Average Cost of Remaining Cows} = \frac{50,000}{8} = 6,250 \]

### Final Answer:
The average cost of the remaining cows is Rs. 6,250.
