Solution:

Since both the block of metal and the block of wood feel equally cold or hot, their temperatures must be equal to the temperature of the body. Otherwise there will be heat flow between the body and either of the blocks. And as the thermal conductivity of the metal is more than that of the wood, it would either feel more hot or more cold than that the block of wood.
