Question

Answer the following:
$\left(i\right)$ There are ${}^{\prime }{a}^{\prime }$ trees in the village Lat. If the number of trees increases every year by ${}^{\prime }{b}^{\prime }$ then how many trees will there be after ${}^{\prime }{x}^{\prime }$ years?
$\left(ii\right)$ For the parade, there are $y$ students in each row and $x$ such row are formed. Then, how many students are there for the parade in all?
$\left(iii\right)$ The tens and units place of a two digit number is $m$ and $n$ respectively. Write the polynomial which represents the two digit number.

Answer 1

$\left(i\right)$ Number of trees in village Lat after $x$ years = $a+bx$

$\left(ii\right)$ Total number of students in parade = Number of rows $\times$ Number of students in each row = $xy$

$\left(iii\right)$ Polynomial representing the two-digit number = $10m+n$
