Question

The cost of 2 kg of apples and 1kg of grapes on a day was found to be₹160. Af
month, the cost of 4 kg of apples and 2 kg of grapes is ₹300. Represent the site
algebraically and geometrically.Draw the graph.​

Answer 1

Step-by-step explanation:

let us consider that price of apple be x & grapes be y

case 1:

2x+y=160 .eq1

case 2:

4x+2y=300

.eq2

divide equation 2 on both sides by 2

2x+y=150

we got two equations 1&3

2x+y=160 &2x+y=150

..eq3

then put simanteniously x and y values

in eq 1 in eq 3

2x+y=160 2x+y=150

x=50

x=50

100+y=160 100+y=150

y=60

x=30

y=50

x=30

60+y=160 60+y=150

y=100

y=90

then mark this point on graph and you will find that both the lines will be parallel to each other.
