# Exercise-4 (Materials price and quantity variance; labor rate and efficiency variance)

P&G company produces large size bags for the use of tourists. Company uses standard costing system to control costs. The standards for materials and labor costs to manufacture 1 bag are as follows:

- Direct materials: 7.2 lbs. @ $5 per lb.
- Direct labor: 0.4 hours @ $20 per hour

During the last month, P&G produced 2,500 large bags. 20,000 lbs. of direct materials were purchased @ $4.8 per lb. There was no direct materials inventory at the beginning and at the end of the month. 900 direct labor hours were recorded @ $24 per hour.

**Required:**

- Compute direct materials price and quantity variance.
- Compute direct labor rate and efficiency variance.

## Solution:

### (1) Materials variances

#### i. Direct materials price variance:

#### ii. Direct materials quantity variance:

*2,500 bags × 7.2 lbs = 18,000 lbs

### (2) Labor Variances

#### i. Direct labor rate variance:

#### ii. Direct labor efficiency variance:

*2,500 bags × 0.4 hours = 1,000 hours
