### Diet Ups and Downs

A woman has been on a diet for a year. In the first month she managed to loose 5% of her weight. In the following 6 months she discovered the heavenly Nutella spread and unable to say "No" to it, gained 5% of her weight. Is she back to where she started?

She will still be %0.25 less than the weight she started with.

How many of you bought Nutella today, reminded of its heavenly taste? I did! Nutella, Dulche-de-leche, Fluff - life could not get any better. I think Alin did as well, as his answer suspiciously lacks the explanation and looks like empirical :) But we count it in anyway as he is right.

Say woman's weight was 100 pounds to start with. After loosing 5% she is down to 95 pounds. Now, she is gaining 5% but not from the original weight of 100, rather from the new weight of 95.

She is now 105 * 95 / 100 = 99.75 pounds
just a bit less than she started from.

Yes or no because she might have not been able to lose any more weight so yes but she might have lost more than 5% in the 6 months.
