This was the first task in the first lesson we had to solve in Math 3 on the University (with strawberries) ^^ It sounds weird but the answer is 50 pounds. But why?
99% water means there is 1% of mass;
if (water == 98%) now {mass == 2%};
==> mass is now weighting
double the amount in relation to water now, which means that the
water is weighting about the half now in absolute numbers.
1 pound mass = 2% ==> 1p / 0,02 = 50 pounds!
