Question

BRIEF SUMMARY: A family consists of mother, father and children. All families are not of the same size. In some families we see grandparents along with mother and father. Normally children resemble their family members. However they might be different in their nature and attitude. Sometimes family members have to live far away due to Job or higher studies. Each family has its own dynasty and surname. Based on the number of people in the family, the family type can be determined like big (joint) family, small (nuclear) family. Help and support will be extended to children with special needs and to the elderly people 1) Observe the picture write the names of your family members and compare them with the members of the family given in the picture.​

Answer 1

Answer:

Let assume that ABCD be the sheet whose

Length, AB = 40 cm

Width, BC = 30 cm

Now, Further given that a border of 3 cm width is printed on a sheet of paper.

Let assume that PQRS be the area of sheet after the 3 cm border.

So,

Length, PQ = 40 - 3 × 2 = 40 - 6 = 34 cm

Breadth, QR = 30 - 3 × 2 = 30 - 6 = 24 cm

Now,

\begin{gathered} \red{\rm \: Area_{(Border)} = Area_{(Rectangle \: ABCD)} - Area_{(Rectangle \: PQRS)}} \\ \end{gathered}

Area

(Border)

=Area

(RectangleABCD)

−Area

(RectanglePQRS)

\begin{gathered}\rm \: = \: AB \times BC - PQ \times QR \\ \end{gathered}

=AB×BC−PQ×QR

\begin{gathered}\rm \: = \: 40 \times 30 - 34 \times 24 \\ \end{gathered}

=40×30−34×24

\begin{gathered}\rm \: = \: 1200 - 816 \\ \end{gathered}

=1200−816

\begin{gathered}\rm \: = \: 384 \: {cm}^{2} \\ \\ \end{gathered}

=384cm

2

So,

\begin{gathered}\bf \: Area_{(Border \: of \: 500 \: sheets)} = 500 \times 384 = 192000 \: {cm}^{2} \\ \\ \end{gathered}

Area

(Borderof500sheets)

=500×384=192000cm

Further given that,

\begin{gathered}\rm \: Cost \: of \: 100 \: {cm}^{2} \: = \: 50 \: paisa \\ \end{gathered}

Costof100cm

2

=50paisa

\begin{gathered}\rm \: Cost \: of \: 192000 \:{cm}^{2} = 192000 \times \frac{50}{100} = 96000 \: paisa \\ \end{gathered}

Costof192000cm

2

=192000×

100

50

=96000paisa

\begin{gathered}\bf\implies \: Cost \: of \: 192000 \:{cm}^{2} \: = \: Rs \: 960 \\ \\ \end{gathered}

⟹Costof192000cm

2

=Rs960
