Answer:
The firm's output prices will increase, because will the firm can quickly adjusts the prices of goods to the new price level of 110, it will not have to do so with wages, since wages are fixed by a year contract.
This will result in comparatively lower labor costs with higher prices at the same time, which will likely result in more economic and accounting profit for the firm.
The opposite effect will be felt by workers, whose wage is not keeping up with inflation, meaning that their income is losing purchasing power.
