Hello aspirant,

Here is the answer to your question.

Marginal costing shows that the meaning of profit gets changed, but here profit means contribution.

Hence, Selling Price= 10 per unit-Variable Cost=6 per unit contribution which is equal to 4 per unit total contribution= 4 per unit * 100000 units= 4 lakhs

So, final profit= 4 lakhs - 2 lakhs (Fixed Cost= 2 lakhs.

Hope, it helps you.
