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.
Solution:
Let cost of 1 kg of apples = Rs x
Let cost of 1 kg of grapes= Rs y
According to given conditions, we have
(1)
(2)
So, we have equations (1) and (2)
and
which represent given situation algebraically.
To represent them graphically, we will find 3 sets of points which lie on the lines.
We plot the points for both of the equations and it is the graphical representation of the given situation.
