Answer :

Ans.Let the cost of cricket bat and cricket ball be Rs.x and Rs.y respectively.

According to the given statement in the question:

=>\(3x + 6y = 3900\)

=>\(x + 2y = 1300\)............(i)

Two solutions of the equation (i) are :

\(\begin{array} {|r|r|}\hline 0 & 1300 \\ \hline 650 & 0 \\ \hline \end{array}\)

And also according to the given statement in the question:

=>\(x + 3y = 1300\)............(ii)

Two solutions of the equation (i) are :

\(\begin{array} {|r|r|}\hline 0 & 1300 \\ \hline {{1300} \over {3}} & 0 \\ \hline \end{array}\)

Now the graph for the above equations (i) and (ii) will be:

- Aftab tells his daughter, “Seven years ago, I was seven times as old as you were then. Also, three years from now, I shall be three times as old as you will be.” (Isn’t this interesting?) Represent this situation algebraically and graphically.
- The cost of 2 kg of apples and 1 kg of grapes on a day was found to be Rs 160. After a month, the cost of 4 kg of apples and 2 kg of grapes is Rs 300. Represent the situation algebraically and geometrically.
