While mining, Jason found a large metal bar that weighed 24 grams. Jason was also able to determine that the bar contained 25% silver. How many grams of silver are in the metal bar?
Answers
20*5=100 , which is 8*5 that is 40.
The weight of silver in the metal bar is 6 grams.
Given: Jason found a large metal bar that weighed 24 grams and the bar contained 25% silver.
To Find: The weight of silver in the metal bar.
Solution:
In this numerical, we use the concept of percentage.
We know that the amount or value of a certain thing can be calculated if we know the percentage of that thing in a group of similar items. This can be shown by;
x % of p = q
Here, we can understand that a certain percentage 'x' of a quantity 'p' is equal to a quantity 'q'. So, q must always be less than or equal to p.
Coming to the numerical, we are given;
The total weight of a metal bar = 24 g
The percentage of silver in the bar = 25 %
According to the concept of percentage, we can find the weight of silver in the metal bar.
The weight of silver in the metal bar = 25 % of 24 g
= ( 25 / 100 ) × 24
= 600 / 100
= 6 g
Hence, the weight of silver in the metal bar is 6 grams.
