Answer:
50% of the solution
Step-by-step explanation:
25% of 100 ml = 25
added to 70 % of (100 - x) = 70 - 0.7x
we need to add 25 + 70-0.7x to get = 100 ml 60% i.e 60
now,
solve for x
0.7x =25+70-60
0.7x =35
x = 35/0.7
x= 50 % of the solution she needs to drain
Answer:
273 people.
Step-by-step explanation:
Given that,
Total number of people working on an office building = 1092
The building has 4 floors, and the same number of people work on each floor.

n = Total number of people/Total number of floors

So, there are 273 people working on each floor.
Answer:
