Answer:
Option (B) is correct.
Explanation:
W.
For finding the variable expenses = change in the cost ÷ change in the quantity
= (10,560 - 8,000) ÷ (140 - 100)
= 2560 ÷ 40
= 64 per unit
total variable expenses for 100 units 64 × 100 = 6400
fixed expenses = 8000 - 6400
= 1600 so it is of MIXED
X.
Here at even different quantity cost is same so it is of fixed expenses
Y.
For variable expenses = (9100-6500) ÷ (140-100)
= 65 per unit
for variable expenses = 65 × 100
= 6,500
so it is of fully variable expenses
Z.
variable expenses = (8,580 - 6,700) ÷ (140 - 100)
= 47 per unit
= 47 × 100
= 4,700
so it is of mixed expenses
