Question

The cost of 2kg of apples and 1kg of grapes one day was found to be rupees 160. after a month, the cost of 4kg of apples and 2kg is rupees 300. represent the situvation algebraically and geometerically​

Answer 1

So, we get 2x+y=160

We are also given that the cost of 4 kg apples and 2 kg grapes is Rs. 300.

So, we get 4x+2y=300

We need to solve the system of linear equations shown below to find the cost of apples and cost of grapes.

2x+y=160

4x+2y=300

Let us find the points that lies on equation

So, we have y=160−2x

Let us find the points that lies on equation

$so \: we \: have \: y = \binom{300}{ - x} by \: 2$

= y=150° - 2x

Let us plot the system of linear equations using the obtained values of x and y-coordinates.
