Direction: Read the following pie chart and table carefully and answer the following questions
The following pie chart shows the percentage of trees in 4 cities in the year 2019.
The following table shows the ratio between Tamarind trees and Tickwood trees in all the four cities if each city has only these two types of tree.
City 
Ratio between the number of Tamarind and Tickwood trees 
P 
3 ∶ 2 
Q 
7 ∶ 3 
R 
3 ∶ 5 
S 
8 ∶ 7 
Total number of Tickwood trees in all the four cities = {(2/5) × (25/100) × 56500 + (3/10) × (28/100) × 56500 + (5/8) × (32/100) × 56500} + {((7/15) × (15/100) × 56500} = 25651
Total number of Tamarind trees in all the four cities = 56500 – 25651 = 30849
∴ Required ratio = (25651/30849) × 100 = 83.15% or 83%
∴ The number of Tickwood tree is 83% of Tamarind tree in all the four cities together
