Dear sir ,im having trouble in section A qu 5 ,how did the answers for yield variance for a n b got 779 and 1168 .and why (1850/0.95)
Then in section B qu 19 how did he calculate the existing capacity for assisstant and junior stylists.
Thank you sirFirst question:
According to the question, for every 19 litres produced they should input 20 litres (8 + 12).
Therefore for production of 1850 litres they should have input 20/19 x 1850 = 1947 litres.
The standard mix is 8 litres of A and 12 litres of B, and therefore the 1947 litres they should have input should have been mixed in the ratio 8/20 of A and 12/20 of B.
I do suggest that you watch my free lectures on mix and yield variances.
Second question:
The salon is open 50 weeks a year, 6 days a week, 8 hours a day.
So the total number of hours is 50 x 6 x 8 = 2,400 hours.
There are two assistants and a cut takes them 0.1 hours. Therefore the capacity of assistants for cuts is (2 x 2,400) / 0.1 = 48,000
It is the same approach for each of them.
