Question

ഒരു മേശയും കസേരയും കൂടി 3000 രൂപയാണ് വില .ഒരു മേശക്കും 4കസേരയ്ക്കും കൂടി 4500രൂപയാണ് വില. ഓരോന്നിനെയും വില എത്രയാണ്?

Answer 1

A table costs Rs. 2500 and a chair costs Rs. 500.

• An equation is said to be linear if the maximum power of the variable is consistently 1. Another name for it is a one-degree equation. A linear equation with one variable has the conventional form Ax + B = 0. In this case, the variables x and A are variables, while B is a constant. A linear equation with two variables has the conventional form Ax + By = C.
• Each term in a linear equation has an exponent of 1, and when this algebraic equation is graphed, it always produces a straight line. It is called a "linear equation" for this reason.

Here, according to the given information, we are given that,

A table and a chair cost Rs 3000. Also, a table and 4 chairs cost Rs 4500.

Let the cost of a table be x and that of a chair be y.
Then, we have,

x + y = 3000 and x + 4y = 4500.

Subtracting one equation from another, we get,

3y = 1500

Or, y = 500 Rs.

Then, x = 3000 - 500 = 2500 Rs.

Hence, a table costs Rs. 2500 and a chair costs Rs. 500.
