Given :
An alloy is a mixture of metals. Suppose that a certain alloy is made by mixing 50 g of an alloy containing 12% copper with 78 g of an alloy containing 92% copper.
To Find :
How many grams of copper are in the resulting mixture what percentage of the resulting mixture is copper.
Solution :
Mass of copper in 50 gm alloy = 
.
Mass of copper in 78 gm alloy = 
.
Total mass of copper, ( 6 + 76.44 ) gm = 82.44 gram.
Percentage of copper in resulting mixture :
Hence, this is the required solution.
A) 2/6 = 1/3
1/3 = 1/3
True
------
b) 1/3 > 2/4
1/3 > 1/2
False
------
c) 1/8 > 3/4
False
------
d) 2/5 < 1/2
True
------
e) 4/12 < 1/6
False
------
f) 3/5 = 7/10
False
------
This is all just a process of simplifying fractions down.
The only 'true' statements there are is option A and D.
