Answer:

Let X be the amount of each metal needed to make 35 Kg of this alloy.

We know that an alloy is composed of nickel, zinc and copper in a proportion

4:1:2. Therefore, we have:

4X+1X+2X = 35

7X = 35

X=\frac{35}{7}

X=5 Kg

Therefore, there are 5 \times 4 =20 kg of nickel, 1 \times 5 =5 kg of zinc, and 2 \times 5 = 10 kg of copper needed to make 35 kg of this alloy

Answer:


Step-by-step explanation:

The ration of weight of nickel, zinc, and copper in an alloy is 4:1:2

The weight of alloy can be written as

4x + x + 2x = 35 Kg

7 x = 35 Kg

X = 35 Kg/7

X = 5kg

The weight of nickel the alloy = 4 x 5 = 20 Kg

The weight of zinc in the alloy= 1 x 5 = 5kg

The weight of copper in the alloy = 2 x 5 = 10 kg

Given,

7x - 8 = 3x + 4

4x = 12

x = 3

Hence, the number is 3.
