A man sold a chair and a table together for Rs.1520, thereby making a profit of 25% on chair and 10% on table. By selling them together for Rs.1535, he would have made a profit of 10% on the chair and 25% on the table. Find the cost price of each.

Let the cost price of each chair and that of a table be x and y respectively.


According to question -


Selling Price of a chair(Profit = 25%) + Selling Price of a table(Profit = 10%) = Rs. 1520




25x + 22y = 30400.....(1)


and,


Selling Price of a chair(Profit = 10%) + Selling Price of a table(Profit = 25%) = Rs. 1520




22x + 25y = 30700.....(2)


Subtracting equation (2) from equation (1), we get -


3x - 3y = - 300


x - y = - 100.....(3)


From equation (3), we get -


x = y - 100


Substituting the value of x in equation (2), we get -


22(y - 100) + 25y = 30700


47y = 32900


y = 700


substituting the value of y in equation (3), we get -


x = 600


Thus, Cost price of each chair and that of a table are Rs. 600 and Rs. 700 respectively.
