[note 1]
std material is 0.16 sq metres; but scrap is 20%.
Thus for 1800
units we need 360 sq metres.
Thus need
input = 0.16/0.8 = 0.2

Variance Analysis
[12 marks]
For each answer,
deduct 0.5 mark
if no F or UF.
Direct labour rate variance = AR*AH - SR*AH = 4,550
U - (1
mark for calculating direct labour rate: $20*1.25 = $25
Direct labour efficiency variance = SR*AH - SR*SH = 250 U
Direct materials usage variance = SP*(AQ-SQ) = 1,260 U (1
mark for calculating SQ – see note 1 above)
Direct material price variance = AQ*(AP-SP) =
$594 F
(b)
Provide one likely explanation each for the direct
material usage variance and the direct labour rate variance
you calculated in requirement (a).
