  1. Seems like 99 percent of 100kg, or 99kg, is the original water weight, leaving 1kg of "other" stuff. 1kg is 2% of 50, so I believe 98% will be water when the total weight is reduced to 50kg through dehydration.

  2. 50 kgs

    x/x-1 = 0.98 - x is the new wt.
    x= 50kgs

  4. 50 kg
    The weight of water reduces not the weight of pulp.
    initially water = 99kg and pulp = 1kg.
    now after dehydration, let water wt = x
    x/(x+1) = 98/100
    therefore x = 49
    total weight of mango = x+1
    hence total weight = 50kg.

    The trick here is that people would assume that wt of pulp would also reduce, while it remains same
