Answer:
Step-by-step explanation:
Given Ratio of numbers = 12 : 13
Let The numbers be 12x , 13x .
Given, Numbers are reduced by 20 .
12x - 20 / 13x - 20 = 2/3
3 ( 12x - 20 ) = 2 ( 13x - 20 )
36x - 60 = 26x - 40
36x - 26x = 60 - 40
10x = 20
x = 2 .
Now, The numbers are 2(12) , 2(13) = 24 , 26 .

Step by step explaination
Given ratio of numbers =12,13.
Let the numbers be 12x,13x.
Given numbers are reduced by 20.
= 12x - 20/13x-20 =2/3
= 3(12x-20)=2(13x-20)
= 36x-60=26x-40
= 36x-26x=60-40
= 10x=20
So x=2
Now, the numbers are 2(12),2(13)=24,26
