I like the solution - it’s helpful. We could also do a simple alligation 110 and 90 building a ratio of 3:1. only one option fits

There is another method to solve this, and that is alligation

+10% -10%
5%
----------------------------
15% : 5%
3 : 1
5% = 1000, Therefore cost price will be 20,000
15000 and 5000 are the only two options solving upon which we can get the right answer as 1000 profit
