Let Cost of $ 1 $ table be $ RsT $ .

Let the Cost of $ 1 $ Chair be $ RsC $ .

From the first statement we can interpret that cost of $ 1 $ table is $ Rs200 $ more than a chair, we can form a equation with the given data using these two variables and a constant

$ T = 200 + C...................(1) $

With the help of 2nd sentence we can form the following equation:

$ 2T + 3C = 1400.................(2) $

Now we can substitute the value of $ T $ from $ Equation1 $ and substitute in the $ Equation2 $ in order to get the value of $ C $ . After finding the Value of $ C $ we can substitute in $ Equation1 $ to find the value of $ T $ .

$ \Rightarrow 2 \times (200 + C) + 3C = 1400...........(3) $

$ \Rightarrow 2C + 400 + 3C = 1400........(4) $

$ \Rightarrow 5C = 1400 - 400.......(5) $

$ \Rightarrow C = 200..........(6) $

Using the value of $ C $ from $ Equation6 $ and substituting in $ Equation1 $ we will get the value of $ T $

$

\Rightarrow T = 200 + 200 \\

\Rightarrow T = 400 \;

The Price of $ 1 $ table is $ Rs400 $
