Answer:
The answer is option A : 5%
Step-by-step explanation:
We have the following information in percentage:
Employees taking winter vacation= 75
Employees taking both winter and summer vacation= 40
Employees taking none vacation = 20
We can assume the situation as following:
Winter + Summer - Both + Neither = 100
We get;
75 + Summer - 40 + 20 = 100
So, summer = 45
45 people take vacations in summer. But 40 of them take vacation in winters too.
So, people taking vacations in summer but not winter means summer only.
This is : 
%
Therefore, the answer is option A : 5%
Answer:
12 dark chocolates
Step-by-step explanation:
Let there are 2x milk chocolates and 3x dark chocolates.
Total no of milk chocolates = 8
ATQ,
2x = 8
x = 4
Dark chocolates = 3x
= 3(4)
= 12
Hence, there are 12 dark chocolates.
Answer:
subtract 7 from both sides
2x < 7- 7
subtract 7 from 7 to get 0
2x < 0
product of two numbers is < 0 if one is > 0 and the other is < 0. since 2> 0, must be < 0.
x < 0
Answer:
Radius of the given circle is r = 2.
Step-by-step explanation:
Given equation of the circle is 
.
Now we need to find the radius of the given circle .
To find that let's compare with the formula of the circle with is 
, where r is the radius.
We get 
take square root of both sides.
Hence radius of the given circle is r = 2.
