Question

A fruit seller had some apples. He sells 40% apples and still has 420 apples. Originally, he had?

Answer 1

If the fruit seller sold 40% of the apples he had originally, that means he did not sell 60% of those apples [note: 100% is all of them].

 

Since 420 = 60% of the number of original apples,                        420=(60/100)x

  then  10% is 70

   and    100% is 700                                                                 (100/60)(420) = x

                                                                                                      700 = x

 

Check:

If the fruit seller had 700 apples and sold 40% (that is, sold 280), he would still have 420 apples (that is, 700-280).
