A group of workers normally consists of 60 men, 30 women and 20 boys. They are paid at standard hourly rates as under: Men Rs. 280.00

Women Rs. 160.00

Boys Rs. 140.00

In a normal working week of 40 hours, the group is expected to produce 5,000 units of output.

During the week ending on March 21, 2021 the group consisted of 70 men, 25 women, and 25 boys. The actual wages paid were Rs. 270, Rs. 165 and Rs. 130 respectively. 4,500 units were produced.

The Company is using Flexible Budgeting.

Calculate:

2(a) Labour cost variance

2(b)Labour rate variance

2(c) Labour efficiency variance

Given:

Standard Number of men = 60

Standard Number of women = 30

Standard Number of boys = 20

Standard hour rate for men = R.s 280

Standard hour rate for women = R.s 160

Standard hour rate for boys = R.s 140

Weekly working hour = 40 hours

Expected unit = 5,000 units

Number of men in march week = 70

Number of women in march week = 25

Number of boy in march week = 25

Actual wage for men = R.s 270

Actual wage for women = R.s 165

Actual wage for boys = R.s 130

Actual units = 4,500 units

Find:

Computation:

Labour cost variance = [SC for AO] - AC

Labour cost variance =  [( 70 × 280) + (25 × 160) + (25 × 140)] - [(70 × 270) + (25 × 165) + (25 × 130)] × 40  

Labour cost variance = (27,100 - 26,275 ) × 40

Labour cost variance =  R.s 33,000 (F)  

Labour rate variance = (SR - AR) × AH worked

Labour rate variance = [(280 - 270)70 + (160 - 165)25 + (140 - 130)25]40

Labour rate variance = [700 - 125 + 250]40

Labour rate variance = [825]40

Labour rate variance = R.s 33000 (F)

Labour efficiency variance = (SH allowed - AH worked)SR

Labour efficiency variance = (0 - 0)SR

Labour efficiency variance = 0
