3.Two buyers want to buy a product from one seller. the value of the product is $500,000. for insurance statement

the first buyer stated the $500,000 but the second buyer stated half of the price ($250,000). By chance both

orders took place in one container and it drowned in water. We know that the first buyer could get the whole
