Hii there!!!
Let the third number be x
First number 20/100×x= 1x/5
1x/5+x= 6x/5
Second number= 50/100×x= 1x/2
1x/2+x= 3x/2
Ratio= (6x/5)/(3x/2)
= 6x/5×2/3x
= 4/5
= 4:5 ANS
Hope it helps dear....

HEY!!!
20/100 = 1/5
50/100 = 1/ 2
more than 3rd = 1/5 +1 = 1/6
more = 1/ 2 + 1 = 1/3
the the value of it = 4 :5
20/100 = 1/5
50/100 = 1/ 2
more than 3rd = 1/5 +1 = 1/6
more = 1/ 2 + 1 = 1/3
the the value of it = 4 :5
