Answer 1

Answer:

26.67$\%$ of Vinegar contains  in the mixture.

Step-by-step explanation:

Given:

Toatl Mixture in Bottle of Salad dressing= 100 ml

80$\%$ Oil in Mixture = $\frac{80}{100}\times100=80 ml$

20 $\%$ Vinegar in Mixture =$\frac{20}{100}\times100=20ml$

Now 40$\%$ is Used of total mixture so 60$\%$ is remaining.

Remaining mixture = 60% = $\frac{60}{100}\times 100=60 ml$

20% of Vinegar in remaining mixture = $\frac{20}{100}\times 60= 12ml$

4ml of vinegar is added in remaining mixture.

Now vinegar quantity in remaining mixture = 12 +4 = 16ml

Percentage of Vinegar contains  in the remaining mixture= $\frac{16}{60}\times 100$= 26.67%
