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.

Find the difference between average number of females visited park A, C & D and total number of males visited park B.

The correct answer is 60.

By analyzing the provided line graph titled "Number of People (Male + Female) Visited Different Parks" and the accompanying fraction table, we can extract the following data points:

Total number of people (male + female) visited:
- Park A = 144
- Park B = 160
- Park C = 112
- Park D = 96

Fraction of males out of the total number of people:
- Park A = $\frac{2}{3}$
- Park B = $\frac{5}{8}$
- Park C = $\frac{4}{7}$
- Park D = $\frac{3}{4}$

Step 1: Calculate the number of females who visited Parks A, C, and D

The fraction of females is given by subtracting the fraction of males from 1.

For Park A:
- Fraction of females = $1-\frac{2}{3}=\frac{1}{3}$
- Number of females in Park A = $144\times \frac{1}{3}=48$

For Park C:
- Fraction of females = $1-\frac{4}{7}=\frac{3}{7}$
- Number of females in Park C = $112\times \frac{3}{7}=16\times 3=48$

For Park D:
- Fraction of females = $1-\frac{3}{4}=\frac{1}{4}$
- Number of females in Park D = $96\times \frac{1}{4}=24$

Step 2: Calculate the average number of females visited Parks A, C, and D

- Average = $\frac{48+48+24}{3}$
- Average = $\frac{120}{3}=40$

Step 3: Calculate the total number of males who visited Park B

- Number of males in Park B = $160\times \frac{5}{8}=20\times 5=100$

Step 4: Find the difference between the two values

- Difference = $100-40=60$
