A first alloy contains x pounds of 55% silver. It is mixed with a second alloy containing 30% silver to make 60 pounds of an all

Ann [662]

Answer:

"24 pounds" is the appropriate answer.

Step-by-step explanation:

According to the question, the equation will be:

⇒ $x+y=60$ ...(equation 1)

or,

⇒ $\frac{55}{100}x+\frac{30}{100}y=\frac{40}{100}\times 60$

$55x+30y=2400$ ...(equation 2)

Now,

By multiplying (equation 1) by 55 and (equation 2) by 1, we get

⇒ $55x+55y=3300$ ...(equation 3)

⇒ $55x+30y=2400$ ...(equation 4)

From equation 3 and 4, we get

⇒ $25y=900$

$y=\frac{900}{25}$

$=36$

By putting the values of "y" in equation 1, we get

⇒ $x=60-36$

$=24$

Thus the value of x be "24 pounds".
