Price of 3 tables and 5 chairs is Tk. 2,000. Again, price of 5 tables and 7 chairs is 3200 Tk. What is the price of 1 table and 1 chair?
(Equation)Let, the price of one table is x Tk.
And the price of one chair is y Tk.
According to the question
3x + 5y =2,000....................(i)
5x + 7y = 3, 200 ……..(ii)
Now, we multiply equation (i) by 5 & (ii) by 3 & subtract equation (ii) from equation (i)
Putting the value of y in equation (i), we get
ans. The price of 1 table is 500 Tk. and 1 chair is 100 Tk.
