Daily maths challenge

This is my maths challenge for today the theme is baking. You have to figure out how many kgs are in each bag and all of the bags have a different amount. This activity was really hard at the start but then I started to get the hang of it. I figured out that bag 1 has 5kgs of flour, bag 2 has 2kgs of flour and bag 3 has 6kgs of flour. Out of 1-5 1 being the easiest and 5 being the hardest, I rate it a... 4 because it was really hard at first and then I understood the riddle and it got a bit easier.
