Question 777342
The ratio is 9:6:3:2
If we add 9+6+3+2, we get the result as 20. So if 1kg of the mixture is divided into 20 parts, 9 parts of it will be flour,6 parts will be butter, 3 parts will be sugar and 2 parts will be nuts.
1kg=1000grams
Therefore (9/20)*1000=450g is flour
          (6/20)*1000=300g is butter
          (3/20)*1000=150g is sugar
          (2/20)*1000=100g is nuts

check: 450+300+150+100=1000
