Answer 2

Given - Weight of 20 boxes

Find - Number of boxes weighing 3.78 kg

Solution - The given problem can be solved using unitary method.

1.26 kg is weight of number of boxes = 20

So, 1 kg is weight of number of boxes =

$\frac{20}{1.26}$

Number of boxes weighing 1 kg = 15.9

Number of boxes weighing 1 kg (round off number as number of boxes can not be in fraction) = 16

Now, number of boxes weighing 1 kg = 16

Number of boxes weighing 3.78 kg = 16*3.78/1

Number of boxes weighing 3.78 kg = 60.48

Again round off to find number of boxes = 60

Therefore, 60 boxes will weigh 3.78 kg.
