Anybody can help as my answer is 30.
The ratio of the number of Donovan's stickers to the number of Hong Yi's stickers is 10:3.
After Donovan gave Hong Yi 1/5 of his stickers, Hong Yi had 30 stickers less than Donovan.
How many stickers did Donovan give it to Hong Yi?

My answer would be 20.
Since HongYi gave 1/5, that makes the ratio 8:5 from 10:3
3 units > 30
2 units or 1/5 of 10 > 20
