Answer 2

Let,

the Cost of Apples per kg = Rs x.

& the Cost of grapes per kg = Rs y.

Given,

2 kg apples and 1 kg grapes cost Rs 160.

2 x Cost per kg of apples + 1 x Cost per kg of grapes = 160

2x + y = 160 ...(1)

Also,

4 kg apples and 2 kg grapes cost Rs 300

4 x Cost per kg of apples + 2 x Cost per kg of grapes = 300

4x + 2y = 300

2(2x + y) = 2 x 150

2x + y = 150... (2)

Now, plotting equations

2x + y = 160...(1)

2x + y = 150...(2)
