    On january 1st of 2003 there were 50 kg of cucumbers in a vegetable store and they were 99% water by mass. On february 1st of 2003 they were 98% water, by mass due to loss of water through vaporization. What was the mass of cucumbers on February 1st of 2003?

    On January 1,2003
    Total mass= 50 Kg
    out of which water @ 99%= 49.5 Kg = 99% * 50
    and remaining solid= 0.5 Kg = 50-49.5

    The solid mass would not change, only water would vaporize

    On February 1,2003

    Solid= 0.5 (same as above)
    This is (100%-98%=) 2% of the total mass

    Therefore total mass= 25 Kg = 0.5/2%
    Mass of water= 24.5 Kg = 25-0.5

    Check:
    % by mass of water= 98% = 24.5/25
    (which is what the problem states)

    Therefore mass (total mass)of cucumbers on Feb 1 ,2003= 25 Kg
