Answer: 4051 girls, 4862 boys and 1570 adults over 50 years of age group attended the festival.
Step-by-step explanation:
Let x denotes the number of girls.
Then, the number of boys = x+811
The number of adults over 50 years of age = x-2481
Now, by considering the given scenario :-
Thus, the number of girls attended the festival = 4051,
Then number of boys = 4051+811=4862
Number of adults = 4051-2481=1570
Answer:
6 L
Step-by-step explanation:
Given two solutions:
1st solution is 90% saline solution. Let the volume of this solution be litres.
2nd solution is 50% saline solution. Volume of this solution = 4 L
Resultant solution is 74% saline.
To find:
The volume of 1st solution = ?
Solution:
Total volume of the 74% saline mixture = (4+) Litres
We can write equation here, as per the percentage of saline in the mixtures.
90% of L + 50% of 4 L = 74% of (
+4)
Therefore, the volume must be <em>6 L</em>.
