The original price of the commodity is: #C_o=Rs492.75#

Explanation:

Three commodities now cost #Rs1700#

One commodity now cost #(Rs1700)/3=Rs566.6bar6#

The cost now is: #C_n=C_o +15%C_o#

#Rs566.6bar6=C_0+15/100 C_o#

#Rs5666bar6=100C_0+15C_o#

#(Rs5666bar6)/115=C_o#

#(Rs5666bar6)/115=C_o#

#Rs492.75=C_o#
