Question

In an alloy of gold and silver the ratio of the amount of gold to the amount of silver is 2:5.

What is the weight of gold in the alloy, if there are 80g of silver?

Answer 1

32

Explanation:

do 80÷5=16 to get unit. Then do 16*2=32

Answer 2

Given :

The ratio of the amount of gold to the amount of silver is 2:5.

To Find :

The weight of gold in the alloy, if there are 80 g of silver.

Solution :

Let, amount of gold is x.

So, the ratio of amount of gold and silver is :

`(x)/(80)=(2)/(5)\\\\x=32\ g`

Therefore, the weight of gold in the alloy is 32 g.

Hence, this is the required solution.
