Question 3:
The cost of 2 kg of apples and 1 kg of grapes on a day was found to be Rs 160. After a month, the cost of 4 kg of apples and 2 kg of grapes is Rs 300. Represent the situation algebraically and geometrically.
Answer:
Let the cost of 1 kg of apples be Rs x.
And, cost of 1 kg of grapes = Rs y
According to the question, the algebraic representation is
2x + y = 160
4x + 2y = 300
For 2x + y = 160,
y = 160 – 2x
The solution table is
For 4x + 2y = 300,
The solution table is
The graphical representation is as follows.
