The cost of 2kg of apples and 1kg of grapes on a day was found to be $160.After a month, the cost of 4kg of apples and 2kg of apples is$300. Represent the situation algebraically

you olve it by the method of linear equation in two variable.then you plot the graph of the solution . agar solve nahi hota to comment kar dena.

olve nahi solve

Let cost of 1kg apple=a.

So cost of 2kg apples=2a

Therefore, cost of 1kg grapes=160-2a

So cost of 4kg apples=4a

And cost of 2kg apples=2a

So total cost=4a+2a=6a

Thus 6a=300

So a=300/6=$50 Setting cost of 1kg grape=160-2a with a=50,we get Cost of 1kg grapes=160-(2*50)=160-100=$60

Therefore, Cost of 1kg apples=$50 And, Cost of 1kg grapes=$60.
