Answer:
option (a) is correct, $ 2400
Explanation:
Given:
Direct materials cost = $ 700
Direct labour cost = $ 1300
Variable overhead = $ 400
Transfer price is relevant cost for Engine division
Now,
the relevant cost is variable cost
Also, variable cost is given as;
variable cost = Direct material + Direct labor + Variable overhead
on substituting the values in the above formula, we get
variable cost = $ 700 + $ 1,300 + $ 400
or
variable cost = $ 2400
Hence, option (a) is correct
