The correct answer is: A. Rs 142,485
The value of the output is calculated as follows:
- Cost of materials used = 3,500 * 20 = Rs 70,000
- Cost of labour = 2,750 * 25 = Rs 68,750
- Cost of normal loss = 3,500 * 0.2 = Rs 700
- Value of normal loss = 700 * 5 = Rs 3,500
- Cost of units produced = 70,000 + 68,750 – 3,500 = Rs 142,485
Therefore, the value of the output is Rs 142,485.
Option A is the correct answer because it is the only option that is equal to the value of the output calculated as above. Option B is incorrect because it is the cost of materials used plus the cost of labour. Option C is incorrect because it is the cost of materials used plus the cost of labour plus the cost of normal loss. Option D is incorrect because it is the cost of materials used plus the cost of labour plus the cost of normal loss plus the value of normal loss.
