Answer:
$740
Explanation:
The computation of phantom profit is shown below:-
According to FIFO,
Closing Stock = (390 × $12) + ( 40 × $11)
= $4,680 + $440
= $5120
According to LIFO
Closing Stock = (350 × $10) + (80 × $11)
= $3,500 + $880
= $4,380
Amount of Phantom Profit
= $5120 - $4,380
= $740
Therefore for computing the phantom profit we simply deduct LIFO from FIFO.
