CHANDIGARH: October, 22 : The PU authority has hiked the food prices by 6-8 Rupees per meal which has increased the burden on the pocket of the students by 700-800 Rupees per month. The price has been increased as a result of increase in the cooking gas prices. We request the PU authority to provide subsidy for the cylinders and do not burden the students as the increase can provoke student upheaval. If University authorities do not take any action then I will go on a hunger strike.
