Answer:
weight of gold = 110 g
weight of silver = 90 g
Step-by-step explanation:
weight of electrum = 200 g
ratio of gold and silver in 200 g of electrum is = 11 : 9
let the weight of each metal = x
i.e.
11x + 9x = 200
20x = 200
x = 200/20 = 10
weight of gold = 11x = 11(10) = 110 g
weight of silver = 9x = 9(10) = 90 g
