Of the 48 oranges in a carton, one-third of them were rotten. ben and david took the remaining good oranges. if ben took 8 more oranges than david, how many oranges did david take?

First you need to find out what is 1/3 of 48 which is 16 
Then 48-16 which is 32
so now you know there are 32 oranges left 
Ben took 8 more then David what do you think answer would be??
