Answer:
Possible causes of material quantity variance:
1. The use of sub-standard material
2. The use of unskilled labour
3. Wastage of material
Step-by-step explanation:
Material quantity variance is the difference between standard quantity and actual quantity used multiplied by standard price. The use of sub-standard material reduces the quality of output thereby resulting to unfavorable material quantity variance. The use of unskilled labour also leads to unfavorable material quantity variance. Wastage of material due to low quality of inputs also results to unfavorable material quantity variance.
