Question

an alloy contains 26% of copper what quantity of alloy is required to get to 260 gram of copper​

Answer 1

Answer:

Let the quantity of Alloy be = x gm

Then, 26% of X = 260 gm

Or 26/100 × X = 260 gm

Or X = (260×100)/26 gm

Or X = 26000/26 gm

Or X = 1000 gm

Answer 2

The quantity of alloy is required to get to 260 gram of copper​ =  1000 gram.

Explanation:

Given : An alloy contains 26% of copper.

Let the quantity of alloy is denoted as  'c'.

Then , the amount of copper = 0.26 c

if we required 260 gram of copper​ , then our equation becomes :

$0.26c=260$

Divide both sides by 0.26 , we get

$c=1000$

Hence, the quantity of alloy is required to get to 260 gram of copper​ =  1000 gram.
