Cost of 2 kg brinjal and 4kg tomato is rs.120. After two days the cost of 4 kgs brinjal and 5 kgs tomato is rs.160. Express this situation in linear equation

Answer 1

Given:

Cost of 2 kg brinjal and 4kg tomato is rs.120. After two days the cost of 4 kgs brinjal and 5 kgs tomato is rs.160.

To find:

Express this situation in linear equation.

Solution:

Let "x" represent the brinjal.

Let "y" represent the tomato.

From given, we have,

Cost of 2 kg brinjal and 4kg tomato is rs.120.

2x + 4y = 120.

After two days the cost of 4 kgs brinjal and 5 kgs tomato is rs.160.

4x + 5y = 160.

Hence the representation of this situation in linear equations.
