Question

Direct Labor Efficiency Variance, Direct Labor Mix and Yield Variances

Vet-Pro, Inc., produces a veterinary grade anti-anxiety mixture for pets with behavioral problems. Two chemical solutions, Aranol and Lendyl, are mixed and heated to produce a chemical that is sold to companies that produce the anti-anxiety pills. The mixture is produced in batches and has the following standards:

Direct Material	Standard Mix		Standard Unit Price		Standard Cost
Aranol	3,000	gallons	$4.00	per gallon	$	12,000
Lendyl	17,000		6.00			102,000
Total	20,000	gallons				$114,000
Yield	16,000	gallons

During March, the following actual production information was provided:

Direct Material	Actual Mix
Aranol	60,000	gallons
Lendyl	140,000
Total	200,000	gallons
Yield	166,000	gallons

Vet-Pro, Inc., also uses two different types of direct labor in producing the anti-anxiety mixture: mixing and drum-filling labor (the completed product is placed into 50-gallon drums). For each batch of 20,000 gallons of direct materials input, the following standards have been developed for direct labor:

Direct Labor Type	Mix		SP		Standard Cost
Mixing	2,000	hrs.	$14.00			$28,000
Drum filling	1,200		9.50			11,400
Total	3,200	hrs.				$39,400
Yield	16,000	gallons

The actual direct labor hours used for the output produced in March are also provided:

Direct Labor	Type Mix
Mixing	18,000	hrs.
Drum filling	12,000
Total	30,000	hrs.
Yield	158,400	gallons

Required:

1. Compute the direct labor mix and yield variances. (Round standard price of yield to four significant digits and mix proportion to three significant digits. Use the rounded numbers in the subsequent computations.)

Mix variance
Yield variance

2. Compute the total direct labor efficiency variance.

Answer 1

1) Computing the direct labor mix and yield variances:
Direct Labor	Actual Hour	SM	Actual Hour-SM	Standard price	(Actual Hour-SM) Standard price
Mixing	18,000	18,750	-750	$14.00	($10,500)
Drum-Filling	12,000	11,250	750	$9.50	$7,125
Mix Variance					($3,375) F

=(150,000 - 158,400)$ 2.4625

=$ 20,685 (F)

2.total direct labor efficiency variance

Total Hours Allowed = 158,400/5

= 31,680

SH (mixing)= 31,680 * 0.625

=19,800 hours

SH (Drum-filling) = 31680 *0.375

=11,880 hours

Direct Labor	Actual Hour	SM	Actual Hour-SM	Standard price	(Actual Hour-SM) Standard price
Mixing	18,000	19,800	-1,800	$14.00	($25,200)
Drum-Filling	12,000	11,880	120	$9.50	$1,140
Yield Variance					($24,060) F

=$ 3,375 +$ 24,060(f)

=$27,435 (F)
