Question

Q1 An alloy contains 14 parts of tin and 100 parts of copper. What is the percentage of tin in the alloy ? 12.28% 13% 11.5% 14%​

Answer 1

Answer:

12.28%

Step-by-step explanation

percentage = parts of tin / total parts of alloy multiplied by 100

percentage = 14/(100+14) * 100

14/114 * 100

12.28%

Answer 2

The answer is option $a) 12.28\%$.

Step-by-step explanation:

The amount of tin present $= 14$ parts

The amount of copper present $= 100$ parts

Thus, the total parts $= 14 + 100 = 114$

The percentage can be found by dividing the particular quantity by the total amount and then the result multiplied by 100.

So, the percentage of tin

$= \frac{14}{114}\times 100$

$= 0.1228\times 100$

$= 12.28\%$

Thus, option $a) 12.28\%$ is correct.
