Let the cost of a chair be x and cost of a table be y
3y+2x=1850
y=x+75
3(x+75)+2x=1850
3x+225+2x=1850
5x=1625
x=1625/5=325
therefore the cost of a chair is rs.325
cost of a table =y=x+75=325+75=400
Therefore the cost of a table is rs.400

Let the table = x+75
Let the chair = x
from the equation we can know that
     3(x+75)+2x = 1850
      3x + 225 + 2x = 1850
      5x = 1850 - 225
       5x = 1625
        x =   1625/5
         x = 325 ⇒ chair = 325, table = x + 75
                                               table = 325 + 75
                                                         =  400 r.s
