A dealer bought two tables for Rs 3120. He sold one of them at loss of 15% and other at a gain of 36%. Then, he found that each table was sould for the same price. Find the cost price of each table.

Cost price of 2 tables = Rs.3120


Let CP of first table = Rs. X


Then, CP of second table would be = Rs. 3120 – x


Let first table is sold at a gain and second at loss.


Selling price of first table =


Selling price of second table =


We have,


=


=221x = 85×3120


= x =


Cost price of first table = Rs.1920


Cost price of second table = 3120 – 1920 = Rs.1200
