1)

Given:

  Total number of units =220\ units

   Percentage of units rejected =20\%

To Find:

Number of agreed units

Step by step explanation:

Number of agreed units = Total \ units - Rejected \ Units

   =220-20\% \ of\ 220\\\\=220-\frac{20}{100}\times 220=220-44=176\ units

  Hence 176 units are agreed units.

2)

Given:

Area of metal sheet that was purchased= 2600 \ cm^2

Percentage of sheets used for making quadrilateral tokens=45\%

Percentage of sheets wasted=24\%

To find:

Quantity of wasted sheet.

Step by Step solution:

  Percentage of sheets used for making circular tokens

   =(100-(45+24) )\%=31\%

   Quantity of sheets that got wasted =24\% \  of \ 1600 \ cm^2

   =\frac{24}{100}\times 1600=384 \ cm^2

    Hence 384 cm² area of the given sheet got wasted.
