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

Find the ratio of total female visited park D to total children visited park C and D together in a week.

The correct option is 9 : 23.

Step-by-Step Solution:

Step 1: Find the value of P

It is given that the total number of adult males who visited all four parks in the week is 2700.
From the table, total males = 80P + 40P + 45P + 15P.

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

$180P=2700$

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

Step 2: Calculate adult males in Park C and Park D

$\text{Adult Males in Park C}=45\times 15=675$

$\text{Adult Males in Park D}=15\times 15=225$

Step 3: Calculate adult females and children for Park C

The ratio of adult males to females in Park C is 9 : 4.

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

$\text{Total Adults in Park C}=675+300=975$

Given total people in Park C = 1200.

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

Step 4: Calculate adult females and children for Park D

The ratio of adult males to females in Park D is 5 : 3.

$\text{Adult Females in Park D}=225\times \frac{3}{5}=135$

$\text{Total Adults in Park D}=225+135=360$

Given total people in Park D = 480.

$\text{Children in Park D}=480-360=120$

Step 5: Calculate the required ratio

Total females visited Park D = 135

Total children visited Park C and D together = 225 + 120 = 345

$\text{Required Ratio}=\frac{135}{345}=\frac{9}{23}$

Therefore, the required ratio of total females in Park D to total children in Park C and D together is 9 : 23.
