How Many Apples?Date: 09/19/2002 at 17:11:25 From: Michelle Kolb Subject: Math riddle word problem John had a part-time job picking apples. One day his boss let him take a box of apples home. Along the way John gave half of his apples plus 3 more to the chairman of a charity bazaar. Later he met Hiko and gave her half of the remaining apples plus 3 more. Finally, John got home and gave his mother half of the remaining apples plus 3 more for an apple pie. After all this, John had 10 apples for himself. How many apples did John get from his boss? I tried to do the problem in reverse and just use several random numbers. My parents even helped me too.

But evidently you had trouble trying to find the answer that way. We don't know why you are having trouble without seeing the work you have tried to do on this. Here is how I might start an answer to this problem by working backwards: 10 = # John ended up with 13 = # he had before he gave those last 3 to his mother 26 = # he had before giving half of what he had to his mother 29 = # he had before giving those last 3 to Hiko ... Did your work look anything like that? - Doctor Greenie, The Math Forum http://mathforum.org/dr.math/ Date: 09/20/2002 at 03:36:16 From: Michelle Kolb Subject: Thank you (math riddle word problem) Thank you from my daughter and me. I think that this is a great service to both parents and students. Karen Kolb |
