Contribution for Standard is $30 per unit and Supreme is $60 per unit, Thus if Fixed expenses are first divided between the two products on the basis of Contribution per unit, It can be calculated as below:
Fixed Expense Bifurcated on basis of Contribution per unit= 30:60
Which Comes to 1:2
Thus it will be bifurcated as $1200000 for Supreme and $600000 for Standard
Thus for Standard to break even it Requires to Sell the below no of units:
Break Even Point in units=

Break Even Point in units=

Break even points in units=20000 units
