Given:
Cost of 2kg of apples and 1kg of grapes is ₹ 240
Cost of 4kg of apples and 2kg of grapes is ₹ 500
To find:
Graphical representation of the Situation.
Solution:
1) Let the price of 1 kg apple is ₹ x
Let the price of 1 kg grapes is ₹ y
2) According to the question:
- 2x+y =240 ---(I)
After a month:
- 4x+2y =500
- 2x+y = 250--(II)
The Solution of the equations graphically.
- 2x+y =240
| x | 50 | 100 |
| y | 140 | 40 |
- 2x+y = 250
| x | 50 | 100 |
| y | 150 | 50 |
The lines of the equations in both condition are parallel to each other.
For the representation refer to the picture.
