The cost of the board = 4x3x12= 144
Cost of the aluminium lining = (4+4+3+3)x4 = 56
So total cost = 200 Rs
Selling price = 200 x 1.25 = 250 Rs

A carpenter bought a rectangular white board of dimension 4 feet x 3 f...
Given:
- Dimension of the white board: 4 feet x 3 feet
- Cost of white board: Rs 12 per square feet
- Cost of fixing aluminum lining: Rs 4 per feet
- Desired profit: 25% on the cost price

To find:
Price at which the carpenter should sell the finished white board

Solution:
1. Calculating the cost of white board:
- Area of the white board = Length x Width = 4 feet x 3 feet = 12 square feet
- Cost of white board = Area x Cost per square feet = 12 square feet x Rs 12 = Rs 144

2. Calculating the cost of fixing aluminum lining:
- Perimeter of the white board = 2 x (Length + Width) = 2 x (4 feet + 3 feet) = 14 feet
- Cost of fixing aluminum lining = Perimeter x Cost per feet = 14 feet x Rs 4 = Rs 56

3. Calculating the total cost:
- Total cost = Cost of white board + Cost of fixing aluminum lining = Rs 144 + Rs 56 = Rs 200

4. Calculating the selling price:
- Desired profit = 25% of cost price = 25% of Rs 200 = Rs 50
- Selling price = Total cost + Desired profit = Rs 200 + Rs 50 = Rs 250

Therefore, the carpenter should sell the finished white board at Rs 250 in order to gain a 25% profit on the cost price. Hence, the correct answer is option B.
