Q 8. An operator is engaged in machining certain components receives an ordinary day rate of `1.60 per day of 8 hours. The standard output for machining the component has been fixed at 80 pieces per hour (time as fixed for premium bonus). On a certain day, the output of the worker on this machine is 800 pieces.

A’s time basic wages are `8 per day, B’s `6 per day and C’s `5 per day. A worked for 25 days, B worked for 30 days and C worked for 40 days. Distribute the amount of `725 among the three workers. Q 10. A skilled workman in Alpha Ltd. is paid a guaranteed wage rate of `30 per hour. The standard time per unit for a particular product is 4 hours. P, a machine man, has been paid wages under the Rowan incentive plan and he had earned an effective hourly rate of `37.50 on the manufacture of that particular product.

He is considering the introduction of some incentive either Halsey scheme (50%) or Rowan scheme of wage payment for increasing the labour productivity to cope with the increased demand for the product by 25%. He feels that if the proposed incentive scheme could bring about an average 20% increase over the present earnings of the workers, it could act as sufficient incentive for them to produce more and he has accordingly given this assurance to the worker.

Hourly rate of wages (guaranteed) `2 Average time for producing one piece by one worker at the previous performance 2 hours (This may be taken as time allowed) No. of working days in a month 25 No. of working hours per day for each worker 8 Actual production during the month 1,250 units Required: 1. Calculate effective rate of earnings per hour under Halsey Scheme and Rowan Scheme. 2. Calculate the savings to Mr. A in terms of direct labour cost per piece under the above schemes. 3. Advise Mr. A about the selection of the scheme to fulfill his assurance. Q 16. Using Merrick’s differential piece rate system, find the earnings of the Amar, Akbar and Anthony for the following particulars: Standard time per piece : 20 minutes Normal rate per hour : `9.00 In a 8 hour day Amar produced : 23 units Akbar produced : 24 units Ali produced : 30 units Q 17.

The hourly wage rate is same for both the workers. In addition workman A is entitled to receive bonus according to the Halsey plan (50%), while B is paid bonus as per Rowan plan. The works overheads are absorbed on the job at `7.50 per labour hour worked. The factory cost of the job comes to `2,600 irrespective of the workman engaged. Find out the hourly wage rate and the cost of raw materials input. Also show the cost against each element of cost included in factory cost. Q 18. Management of a manufacturing unit is considering extensive modernization of the factory through progressive mechanization which would result in improved productivity. Workers would be paid 50% of the improved productivity as incentive wages. It was also agreed that through voluntary retirement the staff strength would be reduced to 300 for the present level of 400. The following further comparative data are available before and after proposed mechanization. Before Mechanization After Mechanization No. of articles produced per month 50,000 48,000 Fringe benefits 50% of wages Wages paid per month `4,00,000 Sales value per month `24,00,000 P/V ratio 25% Based on the above data, you are required to work out the annual financial implications of the proposal.
