  • 1. B = 200 kg

    T = 4%

    N = B × 100 - T/100


    = 200 × 100 - 4/100

    = 200 × 1 - 4

    = 200 - 4

    = 196 kg



    2. B = 80 kg

    N = 76 kg

    T = 1 - N × 100/B

    = 1 - 76 × 100/80

    = -7.599/80

    = -94,98

    = - 95%



    3. T = 2%

    N = 147 kg


    B = N × 100/100 - T

    = 147 × 100/100 - 2

    = 14.700/98

    = 150 kg
