Question

An alloy of Iron and Zinc weighs 40 kg. If the ratio of Iron and zinc are in ratio 5:3, find the quantity of Iron and Zinc in the alloy.

Answer 1

Answer:

Iron = 1.2 kg , Zinc = 1.8 kg when an 3kg alloy of iron and Zinc ... Weight of Iron in 3kg = (40/100) * 3 = 1.2 kg ... Number of zeroes of the polynomial √3x3 - √3 ( ).

Answer 2

Answer:

The quantity of :

→ Iron = 5x = 5(5) = 25kg.

→ Zinc = 3x = 3(5) = 15kg.

Step-by-step explanation:

Given that,

An alloy combination of Iron and Zinc weighs 40kg. Their ratio is 5 : 3 respectively.

Here, the ratio of Iron and Zinc is given which weighs 40kg. We need to find their quantity out of 40kg.

Step 1 :

Considering the quantity of Iron and Zinc as “5x” and “3x”.

Step 2 :

• As their weight is equal to 40kg.

We can say that,

→ 5x + 3x = 40

Step 3 :

Solving for x :

→ 5x + 3x = 40

→ 8x = 40

→ x = 40/8

→ x = 5.

Therefore, we got the value of “x” as 5kg.

• Unit will be in kg.

Hence,

The quantity of :

→ Iron = 5x = 5(5) = 25kg.

→ Zinc = 3x = 3(5) = 15kg.
