The line graph given below shows total number of people (male + female) visited four different parks (A, B, C and D) and table shows fraction of male out of total people visited these four parks.

Read the data carefully and answer the questions below.

Total number of females visited park A and D together is what percent more than total number of females visited park B.

The correct option is 20%.

Let's analyze the visual data provided in both the line graph and the table step-by-step:

1. Extracting values from the line graph:

The line graph shows the total number of people (male + female) who visited four different parks:

• Total visitors in Park A = 144 (point plotted between 128 and 160, exactly at 144)

• Total visitors in Park B = 160

• Total visitors in Park C = 112

• Total visitors in Park D = 96

2. Extracting fractions of male visitors from the table:

The table gives the fraction of males out of total visitors for each park:

• Park A fraction of males = $\frac{2}{3}$, so fraction of females = $1-\frac{2}{3}=\frac{1}{3}$

• Park B fraction of males = $\frac{5}{8}$, so fraction of females = $1-\frac{5}{8}=\frac{3}{8}$

• Park C fraction of males = $\frac{4}{7}$, so fraction of females = $1-\frac{4}{7}=\frac{3}{7}$

• Park D fraction of males = $\frac{3}{4}$, so fraction of females = $1-\frac{3}{4}=\frac{1}{4}$

3. Calculating the number of females in each required park:

• Females in Park A:

$\text{Females (A)}=144\times \frac{1}{3}=48$

• Females in Park D:

$\text{Females (D)}=96\times \frac{1}{4}=24$

• Females in Park B:

$\text{Females (B)}=160\times \frac{3}{8}=60$

4. Total females in Park A and D together:

$\text{Total Females (A + D)}=48+24=72$

5. Percentage by which total females in A and D together is more than females in B:

$\text{Difference}=72-60=12$

$\text{Percentage More}=\left(\frac{72-60}{60}\right)\times 100$

$\text{Percentage More}=\left(\frac{12}{60}\right)\times 100=20\%$

Therefore, the total number of females who visited park A and D together is 20% more than the total number of females who visited park B.
