to get 50% whole wheat 
u add 11% whole wheat and 63% whole wheat in the ratio
(63-50):(50-11)
= 13:39
= 1:3
i.e u add 1 cup of 11% whole wheat to 3 cups of 63% whole wheat to obtain 4 cups of 50% whole wheat
SO
u add 3 cups of 11% whole wheat to 9 cups of 63% whole wheat to obtain 12 cups of 50% whole wheat
