Question

The price of 2 kg apples and 1 kg of grapes is Rs 340 The price of the 3 kg apples and 2 kg grapes is Rs 560 Then find the prince of 1 kg apple and 1 kg grapes Express in linear equations in two variables​

Answer 1

Answer:

Step-by-step explanation:

x  65  55  45  35

y  20  40  60  80

Let the cost of 1 kg of apples be x and that of 1 kg be y

So the algebraic representation can be as follows:

2x+y=160

4x+2y=300⇒2x+y=150

The situation can be represented graphically by plotting these two equations.

2x+y=160⇒y=160−2x

x  70  60  50  40

y=160−2x  20  40  60  80

2x+y=150⇒y=150−2x

x  65  55  45  35

y=150−2x  20  40  60  80
