Find the average number of females visited the park on Friday and Wednesday is how many more or less than the total number of males visited the park on Tuesday.

Read the following pie charts carefully and answer the questions given below. The pie chart (i) shows the percentage distribution of total number of males and females together and pie chart (ii) shows the percentage distribution of total number of females visited in a park on five different days

The correct answer is 30.


From the provided pie charts, we can observe the following total counts and percentage distributions:
• Pie Chart (i): Total number of males and females together = 1500
• Pie Chart (ii): Total number of females = 800

Step 1: Calculate the average number of females visited on Friday and Wednesday
From Pie Chart (ii), the percentage distribution of females is:
• Friday = 25%
• Wednesday = 10%

Number of females visited on Friday = $800\times \frac{25}{100}=200$
Number of females visited on Wednesday = $800\times \frac{10}{100}=80$
Total number of females visited on Friday and Wednesday = 200 + 80 = 280.
Average number of females visited on Friday and Wednesday = $\frac{280}{2}=140$

Step 2: Calculate the number of males visited on Tuesday
From Pie Chart (i), the total visitors (males + females) on Tuesday = 10% of 1500:
Total visitors on Tuesday = $1500\times \frac{10}{100}=150$
From Pie Chart (ii), the females visited on Tuesday = 5% of 800:
Females on Tuesday = $800\times \frac{5}{100}=40$
Number of males visited on Tuesday = Total visitors on Tuesday - Females on Tuesday
Number of males visited on Tuesday = 150 - 40 = 110.

Step 3: Calculate the required difference
Difference = Average females on Friday & Wednesday - Males on Tuesday
$140-110=30$
Thus, the average number of females visited on Friday and Wednesday is 30 more than the total number of males visited on Tuesday.
