Answer 2

Answer:

(i) The cost of 2 kg of apples and 1 kg of grapes is ₹ 160

(ii) The cost of 4 kg of apples and 2 kg of grapes is ₹ 300

Step-by-step explanation:

Let, the cost of 1 kg apples = ₹ x

The cost of 1 kg grapes = ₹ y

The two linear equations can be formed for the above situation.

The cost kg 2 kg of apples and 1 kg of grapes is ₹ 160. Mathematically it can be represented as,

2x + y = 160  ---  Equation(1)

Also, cost of 4 kg apples and 2 kg of grapes are ₹ 300. Mathematically it can be represented as,

4x + 2y = 300

2(2x + y) = 300

2x + y = 150  ---  Equation(2)

Therefore, the algebraic representation for equation(1) is:

2x + y = 160

y = 160 - 2x

And, the algebraic representation for equation(2) is:

2x + y = 150

y = 150 - 2x

For the representation of these equations graphically, we need at least two solutions for each equation. Let's tabulate the solutions as shown below.

The graphical representation is as follows:
