**Reiny**, Monday, June 11, 2012 at 8:44pmheavy package = x

small = (4/3)(x/2) = 2x/3

2x/3 + x = 100

times 3

2x + 3x = 300

5x = 300

x = 60

heavy one --- 60 kg

small one -- - 40

Check:

half the weight of the heavy one is 30 kg

a third of that is 10 kg

a third more than 1/2 the heavey = 10 + 30 = 40

-- all looks good
