Assignment Questions - LABOUR COSTING

Assignment Questions



Question 1.

Using Taylor's differential piece rate system, find the earning of A from the following


Standard time per piece                                                                       12 minutes

Normal rate per hour (in a 8 hours day)                                            Rs. 20

A produced                                                                                           37 Units


Question 2.

Standard output in 10 hours is 240 units; actual output in 10 hours is 264 units. Wages rate is Rs. 10 per hour. Calculate the amount of bonus and total wages under Emerson Plan.


Question 3.

 From the following particulars, calculate the earnings of workers X and Y & labour cost per unit.

Standard time allowed: 20 units per hour

Normal time rate: Rs.30 per hour

Differential to be applied:

80% of piece rate when below standard

120% of piece rate at or above standard

In a particular day of 8 hours, X produces 140 units while Y produces 165 units


Question 4.

Time allowed for a job is 48 hours; a worker takes 40 hours to complete the job. Time rate per hour is Rs.15. Compute the total earnings of the worker under Halsey system.


Question 5.

A worker takes 6 hours to complete a job under a scheme of payment by results. The standard time allowed for the job is 9 hours. His wage rate is Rs.15 per hour. Material cost of the job is Rs.120 and the overheads are recovered at 15% of the total direct wages. Calculate the factory cost of job under

A] Rowan and B] Halsey system of incentive system.


Question 6.

Calculate the earnings of workers A, B and C under the Straight Piece Rate System and Merrick's

Differential Piece Rate System from the following particulars.

Normal rate per hour: Rs.5.40

Standard time per unit: 1 minute

Output per day is as follows.

Worker A – 390 units

Worker B – 450 units

Worker C – 600 units.

Working hours per day are 8


Question 7.

In a factory the standard time allowed for completing a given task (50 units), is 8 hours. The guaranteed time wages are Rs. 20 per hour. If a task is completed in less than the standard time, the high rate of Rs. 4 per unit is payable. Calculate the wages of a worker, under the Gantt system, if he completes the task in

(i) 10 hours; (ii) 8 hours, and (iii) in 6 hours. Also ascertain the comparative rate of earnings per hour under the three situations.



  1. Rs. 122.84
  2. Rs. 130.
  3. X= Rs.168, Rs.1.20 per unit & Y= Rs.297, Rs.1.80 per unit.
  4. Rs.660
  5. a. Rs.258 & b.Rs.249.30
  6.  Straight Piece Rate: A= Rs.35.10, B=Rs.40.50, C=Rs.54.00;

       Merrick's Differential Piece Rate System: A= Rs.35.10, B= Rs.44.50, C= Rs.64.80

  1. i. Rs. 200., Rs. 20 per hour; ii. Rs. 192, Rs. 24 per hour; iii. Rs. 200, Rs. 33.33 per hour.
