The correct answer is A. 5,775.
The material issued on First-in-First out method means that the material that was purchased first is issued first. So, the material issued on 3rd January, 5th January, 15th January and 16th January are all from the first purchase on 1st January. The material returned to stores on 14th January is also from the first purchase.
The total value of the material issued is 300 units * Rs. 12/unit + 124 units * Rs. 12/unit + 250 units * Rs. 12/unit + 300 units * Rs. 12/unit = 1,568 units.
The total value of the material remaining in store on 21st January is 600 units * Rs. 12/unit + 500 units * Rs. 14/unit + 300 units * Rs. 13/unit – 1,568 units = 5,775 units.
