Question

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

Answer 1

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.

Answer 2

Answer:

Hence, we must put 2 pounds in each box.

Step-by-step 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=

$1\times 1+1.25\times 4+2\times 2+2.5\times 2+5\times 1\\\\=1+5+4+5+5\\\\=20$

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.
