Read the following pie charts carefully and answer the questions given below.The pie chart (I) shows the percentage distribution of the total number of tickets sold by five different cinema halls on Sunday. The pie chart (II) shows the percentage distribution of the profit earned by these cinema halls on Sunday.

Note: The average profit of each ticket sold is Rs 30.

The total number of tickets sold by E and C together is what percentage more or less than the total number of tickets sold by B?

First, let us analyze the data from the first pie chart (I) titled "Total tickets sold = 200":

• Percentage of tickets sold by cinema hall B = 25%
• Percentage of tickets sold by cinema hall C = 10%
• Percentage of tickets sold by cinema hall E = 30%

Now, let us calculate the total number of tickets sold by cinema halls E and C together:

$\text{Percentage of tickets sold by E and C together}=30\%+10\%=40\%$

$\text{Total tickets sold by E and C together}=40\%\text{of}200=\frac{40}{100}\times 200=80$

Next, we calculate the number of tickets sold by cinema hall B:

$\text{Total tickets sold by B}=25\%\text{of}200=\frac{25}{100}\times 200=50$

To find how much percentage more the tickets sold by E and C together (80) is compared to B (50), we use the following formula:

$\text{Percentage Difference}=\frac{\text{Tickets sold by (E + C)}-\text{Tickets sold by B}}{\text{Tickets sold by B}}\times 100\%$

Substituting the values:

$\text{Percentage Difference}=\frac{80-50}{50}\times 100\%$

$\text{Percentage Difference}=\frac{30}{50}\times 100\%=60\%$

Thus, the total number of tickets sold by E and C together is 60% more than the total number of tickets sold by B.
