Let’s calculate with the help of how many grams we have the opportunity to represent the mass of gold that is contained in the alloy, whose mass is equal to one hundred and fifty grams, when we reliably know, in accordance with the available data in the conditions of our task, that its percentage in it is 36% :
150 * 36: 100 = 54.
Let’s calculate with the help of how many grams we have the opportunity to represent the mass of silver in it:
150 – 54 = 96.
Answer: It contains 54 g of gold and 96 g of silver.
