Angelina_Jolie [31]

The total number of cookies baked by grandma = 96

Number of grandchildren = 8

As given, all cookies were evenly divided among 8 children, let us assume that everyone except Cindy got equal share. So on being divided equally, it becomes, $\frac{96}{8}=12$ cookies per children.
