at first the weight of the water is 99lb and the cucumber (meat) is 1 lb
at last the cucumber (meat) doen't change, it still one pound and it is 2% of the whole cucumber. therefore the whole cucumber weight 1/2%=50lb

If it is defined as a proportion problem then.
100/99 = x/98
cross multiply
100x=99 x 98 = 9702
x= 97.02 lb,

100 / (.99)density = x / (.98 density)
density cancels
x = .98 (100) / .99
