Ben read 12 books

Firstly you know how any books Sheldon read so to find out number of books Keisha read you go backwards to what they have mentioned.

You times number of books Sheldon has read by 2 then add 4 ( because it says subtract 4 and divide by 2).

(10x2) +4=24

Now we know Keisha has read 24 books and she has read twice as many as Ben therefore number of books Ben has read:

24/2=12

Ben has read 12 books

So Sheldon read 10 so multiply that by 2 (because your doing the opposite of it to find answer) so 2x10=20,
plus 4 =24
So Keisha read 24 books which is twice as many as Ben so divide that by 2 to get the number of books Ben read.
So 24 divided by 2 = 12
Ben read 12 books
