Question

An alloy contains 4% of silver .How many kg of alloy will contain 9kg silver

Answer 1

Answer:

Step-by-step explanation:

Given

Alloy contains 4% of silver

Alloy is the mixture of two or more elements

If silver present is 9kg i.e., 4%

So we have to find the alloy present i.e., 100%

Thus,

Let the weight of alloy in kgs be x

4% of x = 9

4x/100 = 9

4x = 900

X = 225

Therefore,

Weight of alloy in kgs is 225kgs
