From the pie charts given below, find the percentage of each metal. Gold Silver Copper 22 carat

The total weight of 22 carat = 366 . 4 + 20 . 8 + 12 . 8 = 400 g Percentage of gold = 366.4 400 × 100 = 91 . 6 % Percentage of silver = 20.8 400 × 100 = 5 . 2 % Percentage of copper = 12.8 400 × 100 = 3 . 2 %

From the pie charts given below, find the percentage of each metal. Gold Silver Copper 18 carat

The total weight of 18 carat = 112 . 5 + 24 + 13 . 5 = 150 g Percentage of gold = 112.5 150 × 100 = 75 % Percentage of silver = 24 150 × 100 = 16 % Percentage of copper = 13.5 150 × 100 = 9 %

From the pie charts given below, find the weight of each metal. 50 g of 14 carat.

The gold in 50 g of 14 carat = 50 × 59 100 = 29 . 5 g The silver in 50 g of 14 carat = 50 × 4 100 = 2 g The copper in 50 g of 14 carat = 50 × 31 100 = 15 . 5 g The zinc in 50 g of 14 carat = 50 × 6 100 = 3 g

From the pie charts given below, find the weight of each metal. 200 g of 22 carat

The gold is 200 g of 22 carat = 200 × 91.6 100 = 183 . 2 g The silver is 200 g of 22 carat = 200 × 5.2 100 = 10 . 4 g The copper is 200 g of 22 carat = 200 × 3.2 100 = 6 . 4 g The zinc is 200 g of 22 carat = 200 × 0 100 = 0
