Answer :
Ans.Let the cost of 1 kg of apples and 1 kg of grapes be Rs.x and Rs.y respectively.
According to the given statement in the question:
=>\(2x + y = 160\)............(i)
Two solutions of the equation (i) are :
\(\begin{array} {|r|r|}\hline 50 & 45 \\ \hline 60 & 70 \\ \hline \end{array}\)
And also according to the given statement in the question:
=>\(4x + 2y = 300\)
=>\(2x + y = 150\)............(ii)
Two solutions of the equation (i) are :
\(\begin{array} {|r|r|}\hline 50 & 40 \\ \hline 50 & 70 \\ \hline \end{array}\)
Now the graph for the above equations (i) and (ii) will be:
