20kg+24kg+10kg+?kg=?kg

54kg=2?kg

?= 54/2

?=27

Then 27+20+10+24=81

Weight of all = 27 kg
Workings:

Add the two toolboxes containing saw and hammer, 20 + 24 = 44 kg
subtract the weight of saw and hammer, 44 - 10 = 34 kg
Divide the result by 2, since two toolboxes were added, 34/2 =17

To get weight of hammer, subtract 17 from 24, 24 -17 = 7 kg
Do the same for saw, 20 - 17 = 3 kg

The individual weights are:
Saw = 3 kg
Hammer = 7 kg
Toolbox = 17 kg

Total weight = 3+7+17 = 27 kg
