Question

Manish bought 5/14 kg of apples ,3/12 kg of oranges ,and 1/14 kg of mangoes. find the quantity of fruits he bought in all​

Answer 1

Example

y 20 40 60 80

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

So the algebraic representation can be as follows:

2x+y=160

4x+2y=300⇒2x+y=150

The situation can be represented graphically by plotting these two equations.

2x+y=160⇒y=160−2x

x 70 60 50 40

y=160−2x 20 40 60 80

2x+y=150⇒y=150−2x

x 65 55 45 35

y=150−2x 20 40 60 80

We can see that the lines do not intersect anywhere, i.e. they are parallel. Hence we can not arrive at a solution.

Answer 2

Answer:

19/28

Step-by-step explanation:

5/14 + 3/12 = 17/ 28

17/28 + 1/14 = 19/ 28
