To calculate machine hour rate is so easy and very useful for calculating all overheads without checking each and every detail of different overheads. To know what is its process, we are giving following example:
A machine costing Rs. 10000 is expected to run for 10 years. At the end of this period its scrap value is
likely to be Rs. 900. Repairs during the whole life of the machine are expected to be Rs. 18000 and the
machine is expected to run 4380 hours per year on the average. Its electricity consumption is 15 units per
hour, the rate per unit being 5 paise. The machine occupies one fourth of the area of the department and has
two points out of a total of ten for lighting. The foreman has to devote about one sixth of his time to the
machine. The monthly rent of the department is Rs. 300 and the lighting charges amount to Rs. 80 per
month. The foreman is paid a monthly salary of Rs. 960. Find out the machine hour rate, assuming
insurance is @ 1% p.a. and the expenses on oil, are Rs. 9 per month.
Solution
Ist Step
Fixed expenses per month
After searching, the question, you will find five fixed overheads which I showed in Yellow mark. But just finding fixed cost is not sufficient to calculate machine hour rate because we also have to calculate allocate according some basis which is given below
a) Rent : We take only one fourth total rent because our machine takes only one fourth space
300 X 1/4 = Rs. 75.00
b) Lighting : We take one fifth of the total lighting because our machine is using only two points out of total ten points of lighting.
80 X 2/10 = 80 X 1/5 = 16
c) Foreman's salary will be one sixth of total salary because he devote only one sixth of his time for machine.
960 X 1/6 = 160
d) Sundry Expenses - oil, waste etc. 9.00
e) Insurance 10000 X 1% X 1/12 = 8.33
-----------------------------------------------------------
Total Fixed overheads = 268.33
----------------------------------------------------------
2nd Step
Calculate Total Hours of Working
because, we calculate total fixed overheads on monthly basis, so we have also working hours of machine on month basis.
Total number of hours machine used in a year = 4350
Total number of hours per month = 365
Fixed expenses per hour = 268 / 365
= 0.735
3rd Step
To Calculate Variable Overhead per hour
a) Depreciation ( Note : it is not given in question, you calculate it with following formula)
depreciation per hour = cost of machine - scrap / useful life X 1/ total hours of working of machine in a year
= 10000 - 900 / 10 X 1 / 4380 = 0.208
b) Repairs for one hour = 18000 / 4380 X 10 years = 0.411
c) Electricity bill for one hour = 15 units X 0.05 p = 0.750

A resume is what take you to the interview, and an interview is what will follow the offer of that job. From interview you can win a job. And your interviewer can win a competent worker. So keep in mind that you're also there to interview for the prospective employer. You need to find out if this is really where you want to work this thought will help you to relax and be less nervous.
Dress appropriately and be prepared. Relax, be positive, but above all be yourself! Don't dress too casually. Avoid eating, drinking and cigarettes.
Research about the company well before the interview. Meet those people who work in the similar organizations.
Interview yourself in some tape recorder or practice answering the question in front of a mirror.
Until you feel that you've projected your confidence in yourself. Make direct eye contact with the person who is taking your interview. If you don't know about something don't say that you don't know it rather you should say that you want to learn it here. And most important, Don't interrupt the interviewer to jump on some questions you don't know. Answer very clearly.
best of luck,
