The correct answer is 2:5.
I'm explaining bellow 20% means X is multiplied with 100.
For example : 95% of 80 = 80 * 95/100 = 76.
If you are agree with this concept then,
20% = 20/100 and 50/100.
20% = 1/5 and 50% = 1/2
A 1/5 : B 1/2 =2 : 5.
Hence answer is 2 : 5.

Let the third no. Be = 100.
Then add 100 in 20% and 50%.
It will be 120 and 150.
=120 : 150,
= 12 : 15,
= 4 : 5.
Then add 100 in 20% and 50%.
It will be 120 and 150.
=120 : 150,
= 12 : 15,
= 4 : 5.
