Pie Chart Quiz 1

Answer:

According to the pie chart:-

The answer is = 250+195+200+300+275 = 1220

Video solution:

Answer:

Total votes:

= 250+195+200+300+275 = 1220

Votes got by B and D

= 195+300

= 495

So, the answer is

=\frac{495*100}{1220}

= 40.57%

Or, 41% approximately

Video solution:

Answer:

As C got 20% votes so, if 20% of students who voted C vote A then A will get

=250+\frac{200*20}{100}=290

Total votes:

= 250+195+200+300+275 = 1220

So, the answer is

=\frac{290*100}{1220}

=23.77%

or , approximately 24%

Video solution:

Answer:

If 20% of students who voted C vote A

Then C will have

=\frac{200*(100-20)}{100}

= 160 votes

We know that E has 275 votes

So, the answer is

= \frac{160*100}{275}

= 58.18%

or, 60% approximately

Video solution:

Answer:

Total votes of A and B is

= 250+195

= 445

Total votes of C and D is

= 200+300

= 500

Hence the answer is

= \frac{445*100}{500}

=89%

Video solution:

Answer:

We can represent the chart in a table like this:



So, the average salary of all the employees is

=(2500+7500+10000+13000+8000+12500)/6

=8916.67

Or, 9000 approximately

Video solution:

Answer:

We can represent the chart in a table like this:



If we arrange the 6 salaries in ascending order then we will get

2500,7500,8000,10000,12500,13000

So, the 3rd and 4th number in this series is 8000 and 10000

So the median salary is

= (8000+10000)/2

=9000

[The median of n numbers where is even is

[n/2 th term + {(n/2)+1}th term]/2]

Video solution:

Answer:

The salary of D is 13000 and the salary of F is 12500

Hence the answer is

=\frac{(13000-12500)*100}{12500}

= 4%

Video solution:

Answer:

We can represent the chart in a table like this:



To get the minimum value mentioned in the question we need to take the 3 lowest salaries which are 2500,7500,8000

So the answer is:

=(2500+7500+8000)/3

= 6000

Video solution:

Answer:

The combined salary of B and F is

= 7500+12500

= 20000

The combined salary of A and C is

= 2500+10000

= 12500

Hence the answer is

=\frac{(20000-12500)*100}{20000}

=37.5%
