Question

Ten boxes contain cans of different weights. How could you redistribute the cans so each box weighs the same?

Answer 1

Hence, we must put 2 pounds in each box.

Explanation:

It is given that ten boxes contain cans of different weight.

Weight in pounds Number of box

1 1

1.25 4

2 2

2.5 2

5 1

Number of boxes=1+4+2+2+1=10

Total weight of all boxes=

`1* 1+1.25* 4+2* 2+2.5* 2+5* 1\\\\=1+5+4+5+5\\\\=20`

For each box to have equal weight we calculate it as:

Total weight/Number of boxes

=20/10

=2 pounds.

Hence, we must put 2 pounds in each box.

Answer 2

total all the weights by the x's on the chart

total weight = 20 pounds

20/10 = 2

so you could put 2 pounds in each box.
