Answer:
To make an alloy copper and tin are required by weight in the ratio 5 : 2
Let the quantity of copper = 5x
the quantity of tin = 2x
Given, quantity of copper = 31. 5 grams
=> 5x = 31.5
=> x = = 6.3 grams
Quantity of tin added = 2 x 6.3 grams = 12.6 grams
Hence, 12.6 grams tin is to be added with 31.5 grams of copper to get the alloy.
