Let 'a' kg is the weight of the lightest item.
Then, the arrangement of weights in ascending order are:
a, a + 5, a + 10, a + 15, a + 20
Mean = 30
5 x 30 = a + a + 5 + a + 10 + a + 15 + a + 20
a = 20 kg
Weight of heaviest item = 20 + 20 = 40 kg
Sum of weight of lightest and heaviest item = 20 + 40 = 60 kg
