Question

The cost of 2kg apples and 1 kg of grapes on a day was found to be 160 after a month the cost of 4kg of apples and 2 kg of grapes is 300 represent it algebrically and graphically

Answer 1

Let the cost of 1kg of apples be x and cost of 1 kg of grapes be y  

Then the algebraic representation  

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

4x + 2y = 300 ........................(Eqn 2)
