Hello, dear students, welcome to device commerce and management academy.

Today we will see labor mix variants.

Yes, one problem I'll show you but you'll have a good understanding about this formula.

You need to remember a little bit confusing and compared to the other formulas.

This you need to focus a little bit and calculations.

Also one problem, I'm taking it here so problem is very big.

Try to watch it in your computer now see the problem before going to the problem.

Let me tell you the formula labor mixed variance.

The formula is here revised standard hours, minus actual hours both will be in brackets into standard rate, revised standard hours.

How do we calculate for that? There is a formula: revise standard hours is equal to standard hours into total actual hours.

Please remember total actual hours by total standard hours.

So with this formula you will get standard revised standard hours once, if you get it the rest of the things like actual hours and standard at both are given in the problem.

Only this is important point in labor mix.

Variance now let us get into the problem now.

Here is the problem.

Uh, the standard, labor composition and actual labor composition engaged in 10 weeks for a job for a job are as under.

So here what is given standard and actual standard actual? What is this standard actual grade of a b c three grades? Are they three grades related information number of workers? Workers are given: okay and weekly wage rate, 80 70, 50 weekly wage rate is given number of workers of actual workers and standard workers, and this is 50.

60, 10 and weekly wage rate is 70, 75, 60.

and downside.

They are saying this work is actually completed in 12 12 weeks expected how many weeks, 10 weeks they have expected, but it is completed, actually completed in 12 weeks here.

What is given to us here number of workers is given this standard rate is given, but standard hours are not given standard hours.

Not given standard rate is here.

This is standard rate workers, but not ours.

We have to calculate ours in the same actual workers are given and the weekly wage rate means actual rate.

Actual rate standard rate is given.

We need to prepare a table.

Why do we need to prepare the table means because to know the total actual hours total standard hours are needed and also there is a actual actual hours and standard hours both are not given.

So to know that we are preparing one table.

So this is the table.

I already prepared calculation of various labor variances now grade wise.

I have put it in one column and standard hours standard awards.

How do we get standard hours are not given standard rate is given standard hours are not given.

How do we get standard awards? So standard hours is workers into how many weeks are there 10 weeks, each worker is working for 10 weeks.

So if you calculate 40 into 10, you'll get standard hours so 40 into 10.

You got standard hours in the same way.

50 into 10 standard hours of b now see 30 into 10 300.

You got it and standard rate as it is whatever is given.

I have written over there in the same way.

For now, first, we have calculated standard cost.

Standard cost is standard hours into standard rate, multiplied 400 into eighty thirty, two thousand five hundred into seventy thirty.

Five thousand three hundred fifty fifteen thousand up to here I'll write double column up to here.

Standard is over in the same way, now coming to the actual actual hours we have to calculate like we have calculated standard version actual hours.

How do we calculate number of workers into actual completed weeks are 12 that was 10 weeks, so we have multiplied with 10 now.

Actually it is 12 weeks so 15 to 12.

It comes to 600 for a grid in the same way, 16 to 12 720 for b grid and 10 into 12 120 standard hours.

Once if you get the standard hours, actual rate is already given 50, sorry, 70, 75, 60, actual rate okay, 70 75 60, that's written now, total actual cost 600 into forty two, seven twenty into seventy five.

Fifty four thousand one twenty to sixty seven thousand two hundred like you've got this table once.

If you prepare this table, it will be easy for us to calculate the labor mixed variance.

What is the formula for labour mixed variance, revised standard rate minus actual hours into standard rate? Okay, the same formula? I have written first, what we need anyway, this actual hours and standard hours we have in this table revised standard hours.

We have to find out to find out revised standard hours.

This is the formula.

So, as per this formula for grade a, we have calculated so devise the standard hours revise standard hours for grade a.


What is the formula standard hours? Standard hours means here? It is 400, so 400 is written into total actual hours, total actual hours.

Are this one 1400 1400 written divided by total standard hours, total standard hours means 1200, so 1200 is written over there like you've got if you calculate it, you're getting 480 in the same way for b b is here uh? What is this 400 standard hours standard hours are here here a grade 400.

We have written for b grade 500, and this is same as it is, so you are getting 600 in the same way for b c c it is here, 300 300 is written.

This is as it is, so you are getting answer of 360.

once if you gets revised standard hours now put it in the formula.

What is the formula revise standard hours into actual hours into sorry, revise standard hours, minus actual hours into standard rate, so for abc separately? I have done now.

First, one is that revised standard hours revise standard hours of a is 480.

480 is written, minus actual hours.

Actual hours are here, 600 600 into standard rate standard rate is here 80.

This is for a this line: okay, you're getting answer of 9600 unfavorable.

In the same way for b you are getting 8400 unfavorable and for c grade you are getting 12 000 favorable.

Am I clear, confused practiced watch this video once again practice.

It remember this formula first main thing, so this is okay, revise standard hours, minus actual hours into standard rate, but revise standard hours.

How do we calculate this formula? You have to be careful, revise standard hours, standard hours into total actual hours by total standard hours.

That's it take a screenshot or note down by this we have completed today, labor variances.

There is labor yield variance also, I am not finding the proper problem, so that is why I am omitting it if you find it in your test book and ask for my material.

So I'm not finding it I'm following management accounting applications, so I'm not finding proper one for the material yield, variance.

Okay, the rest of all the variances labor variances we have covered successfully.

Am I clear in the coming classes, we'll see more manageable, accounting related topics? Stay connected, don't forget, to share this videos practice well and have a bright career.

Good luck.
