ratio of ages of Ryan and Simon
after 12 years?
1:2
3:7
7:9
9:19​

Answer 1

Answer:

given ratio of present age= 1:2

let ages be x,2x

5yrs back ratio was 1:3

so 5yrs back ages be x-5/2x-5 = y/3y

so after 5 yrs ages are x+5/2x+5

by solving we get 1st age = 10yrs ,2nd age = 20yrs.

so after 5yrs ratio = x+5/2x+5 = 15/25 = 3/5 = 3:5

Answer 2

Answer:

(5x+12)/(8x+12)=22/28= 27/36=32/44---------------------approximately--7:9
