Answer:

The temperature will slightly less than 40°C. Explanation: Because water expands when heated, 1 litre of water at 50°C will have less mass than 1 litre of water at 30°C. As a result, the 30°C litre has slightly more than the 50°C litre, and thus the average will end up slightly less than 40°C.
