Math Question ;-;

I have a math question to ask. I don't know how to do it, but I just know the answer.

A farmer owns chicken and ducks. The ratio of chickens and ducks is 1:2. The farmer then sold 20 ducks and bought 67 chickens. The ratio afterwards for chicken and ducks is 7:3.

i did guess and check and I got 93.

I am not sure I kinda lost my primary school maths skills (wait are you in sec sch or primary sch are you even from singapore ??) and for the original ration , just multiply a number until you can divide the 20 and 67 with it lol . do you get me ?
