Hi Sir,

I have gone over this question a number of times and I cant seem to figure out how the Gross Profit was allocated instead of being charged full to the product:

2 products A and B are produced in a process. Data for the process for the last period are as follows:

Product A:(sales 480 tonnes) (production 600 tonnes)

Product B: (sales 320 tonnes) (production 400 tonnes)Common production costs in a period were $12000. There was no opening inventory. Both products had a gross profit margin 40%. Common production costs were apportioned on a physical basis.

What was the gross profit for product A in the period?

A $2304

B $2880

C $3840

D $4800The correct answer is C

I have been able to calculate cost for product A by ( 600/1000 tonnes X $12000 = $7200) and then I multiplied 7200x 480/600 to get the cost of 5760. To get the gross profit I multiplied 5760*40/100 which would have given me A- 2304. But my answer is wrong as the explanation for the Gross profit is to multiply it by 40/60*5760 which yields C. But I don’t understand why. Would you be able to assist me please?

December 16, 2020 at 4:06 pm #600132For every $100 of sales, the profit is $40 and therefore the cost is $60.

Putting it the other way round, for every $60 cost, the profit will be $40 (and therefore the selling price will be $100).

So for cost of 5,760, the profit will be 40/60 x 5,760.
