y-2/3y=10
1/3y=10
y=30
x=2/3y =2/3(30) = 20

Solution: If we are allowed to use only lower case letters, then we have 26 letters available with us. From these 26 letters the number of different arrangements of 6 letters is:

Now if we are allowed to use only upper case letters, then we have 26 letters available with us. From these 26 letters the number of different arrangements of 6 letters is:

if we are allowed to use both upper case and lower case letters, then we have 52 letters available with us. From these 52 letters the number of different arrangements of 6 letters is:
