Answer 1

Opportunity cost of production of a commodity refers to the cost which the producer has to sacrifice in terms of the next best alternative which could be produced out of that cost in order to produce every unit of the given commodity. Therefore, the opportunity cost for celebrating birthday will be the total amount spent on the birthday occasion which is 400+20= 420 rupees.
