$\begin{gathered}\tt {\blue{Given}} \begin{cases} \sf{\green{200 \: Students \: of \: class \: 6 \: and \: 7}} \\ \sf{\orange{They \: asked \: their \: favourite \: colour}} \\ \sf{\pink{They \: have \: tell \: their \: favourite \: colour}} \\ \sf{\purple{What \: will \: be \: the \: colour \: of \: school \: building}} \end{cases}\end{gathered}</p><p>$

$\begin{gathered}\tt {\blue{To \: Find}} \begin{cases} \sf{\green{Represent \: the \: given \: data \: on \: a \: bar \: graph}} \\ \sf{\orange{Which \: is \: the \: most \: preferred \: colour }} \\ \sf{\pink{Which \: is \: the \: least \: preferred}} \\ \sf{\purple{How \: many \: colours \: are \: there \: in \: all }} \\ \sf {\red{What \: are \: they \: name \: all \: colour}} \end{cases}\end{gathered} </p><p></p><p>$

$\begin{gathered}\tt {\blue{Solution}} \begin{cases} \sf{\green{Bar \: graph \: is \: in \: the \: attachment}} \\ \sf{\orange{Blue \: is \: the \: most \: preferred \: c olour}} \\ \sf{\pink{Green \: is \: the \: least \: preferred \: colour}} \\ \sf{\purple{There \: are \: five \: colour }} \\ \sf{\red{They \: are \: Red,Green,Blue,Yellow \: and \: Orange}}\end{cases}\end{gathered}$

Choose a suitable scale as follows :

⠀

Start the scale at 0. The greatest value in the data is 55, so end the scale at a value greater than 55, such as 60. Use equal divisions along the axes, such as increments of 10. You know that all the bars would lie between 0 and 60. We choose the scale such that the length between 0 and 60 is neither too long nor too small. Here we take 1 unit for 10 students.

⠀

We then draw and label the graph as shown :

⠀

From the bar graph we conclude that

⠀

(i) Blue is the most preferred colour

⠀

(Because the bar representing Blue is the tallest)

⠀

(ii) Green is the least preferred colour

⠀

(Because the bar representing Green is the shortest)

⠀

(iii) There are five colours

⠀

(iv) They are Red, Green, Blue, Yellow and Orange

⠀

(These are observed on the horizontal line)
