Table given below shows total number of people (Adult + Children) visited four different parks in a week. The table also shows total number of males and ratio of male to female in adult people. Read the data carefully and answer the questions.

Parks	Total people (Adult + children)	Total number of males	The ratio of total number of males to that of females in adult people
A	2200	80P	----
B	1440	40P	----
C	1200	45P	9 : 4
D	480	15P	5 : 3

Note: (i) Adult = Male + female
(ii) Total number of adult males visited all four parks in the week = 2700

If total females visited park A are 255 more than that of total children visited park C, then find total children visited park A.

The correct option is 520.

Step 1: Determine the value of $P$ using the total number of adult males.

From the given table, the total number of males visited all four parks (A, B, C, and D) is given as 2700.

The total number of males for each park is represented in terms of $P$ as follows:

Park A: $80P$
Park B: $40P$
Park C: $45P$
Park D: $15P$

Summing these values:

$80P+40P+45P+15P=2700$

$180P=2700$

$P=\frac{2700}{180}=15$

Step 2: Calculate the number of adult males in each park.

Using $P=15$:

Adult males in Park A = $80\times 15=1200$
Adult males in Park C = $45\times 15=675$

Step 3: Calculate adult females and children for Park C.

For Park C, the ratio of adult males to adult females is given as 9 : 4.

$\text{Adult females in Park C}=675\times \frac{4}{9}=300$

Total adults in Park C = Adult males + Adult females = $675+300=975$

From the table, Total people (Adult + Children) visited Park C = 1200.

$\text{Total children in Park C}=1200-975=225$

Step 4: Calculate total females and total children in Park A.

According to the given condition, total females visited Park A are 255 more than total children visited Park C:

$\text{Total females in Park A}=225+255=480$

Since Note (i) states that Adult = Male + Female:

$\text{Total adults in Park A}=1200+480=1680$

From the table, Total people (Adult + Children) visited Park A = 2200.

$\text{Total children in Park A}=2200-1680=520$
