Question

COST OF 2 KG APPLES AND 5 KG ORANGES IS RS- 300. LET COST OF 1 KG APPLE BE RS-X AND THAT OF 1 KG ORANGES IS RS.Y. WRITE THE GIVEN DATA IN THE FORM OF LINEAR EQUATION IN TWO VARIABLES.​

Answer 1

Answer:

show the given data in the form of linear equation in two variables will be

2 X + 5 y = 300

and X + Y =0

Answer 2

 x 65 55 45 35y 20 40 60 80Let 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 802x+y=150⇒y=150−2x

 x 65 55 45 35 y=150−2x 20 40 60 80We can see that the lines do not intersect anywhere, i.e. they are parallel. Hence we can not arrive at a solution.
