Sol:
Calculation of various parts of question is as follows :-
1) Calculation of Contribution & Contribution ratio :-
2) Calculation of BEP in units & dollars :-
3) Calculation of Margin of Safety in dollars & ratio
:-
* Here the total sales is considered as 100 & BEP sales are
deducted from it to get MOS sales ratio.
BEP sales % = BEP sales/Total sales * 100
4) Calculation of additional units to be sold for earning 10%
extra income :-
So additional units to be sold = 331400-320000 = 11400
units.
Here Desried contribution = Net profit required + Fixed costs
so Desried contribution = (39900*1.10) + 721000 = $ 1159900.
5)Calculation of increase in income after increase in sales by
64000 units & other factors remaining constant :-
Increase in income = $632000 - $399000 = $
224000
