Answer:
Ratio of tin to silver in the bar is 2:3
Step-by-step explanation:
We are given the following in the question:
10 kg of tin loses 1.375 kg in the water
Percentage of weight lost by tin =
![\dfrac{1.375}{10}\times 100\% = 13.75\%](https://tex.z-dn.net/?f=%5Cdfrac%7B1.375%7D%7B10%7D%5Ctimes%20100%5C%25%20%3D%2013.75%5C%25)
5 kg of silver loses 0.375 kg
Percentage of weight lost by silver =
![\dfrac{0.375}{5}\times 100\% = 7.5\%](https://tex.z-dn.net/?f=%5Cdfrac%7B0.375%7D%7B5%7D%5Ctimes%20100%5C%25%20%3D%207.5%5C%25)
20 kg bar loose 2 kg in water.
Percentage of weight lost by metal =
![\dfrac{2}{20}\times 100\% = 10\%](https://tex.z-dn.net/?f=%5Cdfrac%7B2%7D%7B20%7D%5Ctimes%20100%5C%25%20%3D%2010%5C%25)
Let x be the amount of tin and y be the amount of silver in bar.
Thus, we can find the ratio as:
![\dfrac{x}{y} = \dfrac{\text{Silver's loss - Average loss}}{\text{Average loss - Tin's loss}}\\\\\dfrac{x}{y} = \dfrac{7.5-10}{10-13.75} = \dfrac{2}{3}](https://tex.z-dn.net/?f=%5Cdfrac%7Bx%7D%7By%7D%20%3D%20%5Cdfrac%7B%5Ctext%7BSilver%27s%20loss%20-%20Average%20loss%7D%7D%7B%5Ctext%7BAverage%20loss%20-%20Tin%27s%20loss%7D%7D%5C%5C%5C%5C%5Cdfrac%7Bx%7D%7By%7D%20%3D%20%5Cdfrac%7B7.5-10%7D%7B10-13.75%7D%20%3D%20%5Cdfrac%7B2%7D%7B3%7D)
is the required ratio.
