Please could you explain why the answer is d) and not c) to the following question:
Jc co operates a bottling plant. The liquid content of a filled bottle of product is 2 litres. During the filling process there is 30% loss of liquid input due to spillage and evaporation. The standard price of the liquid is $1.20 per litre. The standard cost of the liquid per bottle of product T, to the nearest cent, is
A. $2.49 B. $2.86 C. $3.11 D. $3.43
The solution talks about loss of input and not output but I don’t understand the difference nor the calculation!
