Which follow from application of the undermentioned legal principle:
FACTUAL SITUATION: A contracts with B to sell him 1,000 tonnes of iron at Rs.100/− per tonne. B tells A that he needs the iron for export purposes, and that he would be selling the iron at Rs.200/− per tonne. A breaks the contract. When the question comes about damages, A says he will pay only Rs.5000/− as damages because the same variety of iron was available in the market at Rs.105/− per tonne. B however contends that he should be given Rs.1,00,000/− because that was the profit which he would have made had A fulfilled the contract. B had actually bought the iron at Rs.110/− and had exported it.
How much damage is B entitled to get?
