Verified answer

let's find the percentage of red apple so,

20/3 = 6.66 = red apple

100-(20+6.66) = 86.66% is yellow apple

mark me as brainliest

if you don't understand answer again as want proper explanation as I don't have much time

The percentage of yellow apples in the garden is 73.33%

Given:

In a garden of apples, 20% of the apples are green

and the remaining are yellow and red apples

The green apples are thrice as much as the red apples

To find:

What percentage of the total apples are yellow

Solution:

Let us assume that there are 100 apples in the garden

Given that 20% of the apples are green

=> Number of green apples = 20% of 100

= [tex]\frac{20}{100} \times 100[/tex]  = 20

Given that    

The green apples are thrice as much as the red apples

=> Green apples = 3(Red apples)

=> Red apples = (Green apples)/3

=> Red apples = 20/3  

From above calculations

Number of yellow apples = (100 - 20 - 20/3)

= 80 - 20/3

= 220/3

=> Percentage of yellow apples

= (No of yellow apples / Total apple) × 100

= [tex]\frac{ \frac{220}{3} }{100} \times 100[/tex]

= 220/3

= 73.33%

Therefore,

The percentage of yellow apples in the garden is 73.33%
