Question

The cost of two pizzas and one burger is Rs 400. Form a linear equation in two variables for the given situation and draw the graph. Also, from the graph, find the cost of 1 burger if the cost of 1 pizza is Rs 150.

Answer 1

Given :

The cost of two pizzas and one burger is Rs 400

The cost of 1 Pizza = Rs 150

To Find :

The cost of 1 burger

Solution :

Let The cost of pizza = Rs p

The cost of burger = Rs b

Now,

∵ The cost of 2 pizzas and 1 burger = Rs 400

i.e  2 p + 1 b = Rs 400                 ...........1

∵ The cost of 1 Pizza = Rs 150

∴The cost of 2 Pizza = Rs 150 × 2

                                  = Rs 300

From eq 1

2 p + 1 b = Rs 400

Rs 300 + 1 b = Rs 400

Or,  1 b = Rs 400 - Rs 300

Or, 1 b = Rs 100

So, The cost of 1 burger = Rs 100

Hence, The cost of 1 burger is Rs 100  . Answer
