If temperature decreases then thermal tensile stresses induced.

Tensile, when both the ends are fixed in cooling. Compressive, when both the ends are under restriction during heating. If no restrictions there is no stress will develop.

If end conditions are not given then what should we assume (fixed or free) ? Please explain me.

When the bar is cooled. It has been prevented for expansion. So it is try to expands. So there will tensile stress is produced.
