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?

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
