Answer 1

There are two types of direct material variance.
(a) Direct material price variance
(b) Direct Material quantity variance
Direct Material Price Variance
= (Standard price- Actual price)* Actual Quantity
=(5.30-5.10)*262500
=52500 (F)
Direct Material Quantity Variance
= Standard price * (Standard Quantity- Actual Quantity)
=5.3(265200-262500)
=14310 (F)
Total Direct Material Variance
= (Standard price* Standard Quantity)- (Actual price* Actual Quantity)
=(5.3*265200)-(5.1*262500)
=66810 (F)
There are two types of direct labour variance.
(a) Direct labour price variance
(b) Direct labour quantity variance
Direct Labour Price Variance
=(Standard rate-Actual rate)* Actual Hours Worked
=(16.8-17.10)*19950
=5985(U)
Direct Labour Quantity Variance
= Standard rate( Standard hours-Actual hours worked)
=16.8(19500-19950)
=7560(U)
Total direct Labour variance
=( Standard rate* Standard hours)- (Actual rate* Actual hours worked)
=(16.8*19500)-(17.1*19950)
=13545(U)
Variable overhead Controllable variance
=Actual overhead expense-( budgeted overhead p.u* standard no. of units)
=55980-(2.9*19500)
=570(F)
Fixed Overhead absorption rate
=4.6 per labour hour
Fixed overhead volume variance
=Actual overhead incurred-(budgeted overhead p.u*Standard hors)
=93610-(4.6*19500)
=3910(U)
Total Factory Overhead Cost Variance
= Total budgeted cost at standard hours- Total Overhead incurred
=19500*( 4.6+2.9)-(93610+55980)
=3340(U)
